Appropriation of Romeo and Juliet
Discuss the appropriation of ââ¬ËRomeo and Julietââ¬â¢ by William Shakespeare and ââ¬ËRomeo+Julietââ¬â¢ by Baz Luhrmann Texts and ideas from texts are appropriated and transformed into other text forms and other compositions in a different context. An appropriation is a text that is appropriated or taken over by another composer and presented in a new way. Romeo and Julietââ¬â¢ is a well-known high culture text that is a tragedy about two young star-crossed lovers whose deaths ultimately unite their feuding families. In the 1997 film, Baz Luhrmann has taken what is valued about the original play of ââ¬ËRomeo and Julietââ¬â¢; the themes, evocative language and poetry, the timeless storyline and humour, and has placed it in a context which is accessible and appealing to a modern audience.This essay will demonstrate how and why Shakespeareââ¬â¢s ââ¬ËRomeo and Julietââ¬â¢ has been appropriated and valued for modern audiences in relation to: variations in the reactions to the text over time, differences and similarities between language, settings, prologue and chorus, themes, characterisation, techniques, values and contexts, as well as different readings of the play and other appropriations. Shakespeareââ¬â¢s time was an age of great change, as the old ways were being questioned, and more than any other Renaissance figure, Shakespeare exposed an ability to use the past and shape it for his own dramatic needs.As a result of this, his ideas and storyline in ââ¬ËRomeo and Julietââ¬â¢ were being questioned. The earliest registered critic of the play was diarist Samuel Pepys who, in 1662 wrote: ââ¬Å"it is a play of itself the worst that I ever heard in my lifeâ⬠. Ten years later, the poet John Dryden wrote ââ¬Å"Shakespeare showââ¬â¢d the best of his skill in his Mercutioâ⬠, praising the play and its comic character Mercutio. In the mid-18th century, writer Charles Gildon and philosopher Lord Kames argued that the p lay was a failure in that it did not follow the classical conventions of drama.However, writer and critic Samuel Johnson thought it to be one of Shakespeareââ¬â¢s ââ¬Å"most pleasingâ⬠plays. It is evident that ââ¬Å"Romeo and Julietâ⬠has received mixed reactions, but also gained value by responders as the context has changed over the years. In ââ¬ËRomeo and Julietââ¬â¢, Shakespeare applied two specific aspects of life in Renaissance Italy to create the complication of his play. The first was the history of bloody interfamily disagreements that degraded Italian cities uring the Renaissance era, and the second was the fashionable approach to love, based on the poetry of Petrarch (1304-1374, an Italian poet who wrote about love). However, Shakespeare does not simply adopt and recount history; instead he modified the civil wars of the period into a minor war; a family feud that takes place in a stable state. Also, he contrasted the fiction act of the Petrarchan lo ver with the experience of a young man who is truly in love (Romeo). Baz Luhrmann approaches his new version of ââ¬ËRomeo+Julietââ¬â¢ with the same intent.He entertains contemporary viewers by using modern ideas to convey the values embodied in the play and the impossible love, hate and sorrow that are the essence of Shakespeareââ¬â¢s tragedy. Introducing these same ideas in a different context has proven the value of Shakespearesââ¬â¢ storyline and the importance of the morals associated with it. An aspect of Shakespeareââ¬â¢s play and Luhrmannââ¬â¢s film that varies is the setting. The play is set in the 16th century in Verona, whilst Baz Luhrmannââ¬â¢s film takes place on Verona Beach, 20th century times, resembling Los Angeles.The setting of the film is a striking contrast to the Elizabethan England of William Shakespeare; hence the attitudes expressed in the film vary from those conveyed in the play. This also contributes in articulating the contemporary at titude to religion, violence, duty, etc and how it has significantly changed from those of 16th century England. A major feature that Luhrmann has maintained in his film is the original Shakespearean language that characterises the play.Although the meaning of particular sentences has been changed, other parts have been emphasised. An example is Mercutioââ¬â¢s speech at Sycamore grove, the dialogue is very similar, ââ¬Å"Her wagoner [Queen Mab], a small grey-coated gnatâ⬠¦ And in this state she gallops night by nightâ⬠and this has been reiterated by close up shots of Mercutioââ¬â¢s face, showing his emotions. Also the famous line; ââ¬Å"O Romeo, Romeo! ââ¬â wherefore art thou Romeo? â⬠is from the original play and has been reinforced by an offer gaze from Juliet, showing her love for Romeo.This shows contemporary audiences Luhrmannsââ¬â¢ ability to capture the core of the tragedy through traditional Shakespearean text, and that even though the context has changed over the years, the language of Shakespeare is highly valued and pondered by the majority of people. In addition, a difference in the film by Baz Luhrmann, compared to the play by Shakespeare is the prologue and chorus. In Shakespeareââ¬â¢s original production, the chorus would have entered the Globe Theatre, and to gain the audiencesââ¬â¢ attention, would yell ââ¬Å"Two households, both alike in dignityâ⬠and the rest of his part.In Luhrmannsââ¬â¢ portrayal of the chorus, he instead uses close up shots of a television with an African American woman delivering a news report. Whereas Shakespeareââ¬â¢s audience were aurally dependent, modern audiences rely immensely on visual aspects of Luhrmannsââ¬â¢ ââ¬ËRomeo+Julietââ¬â¢. The use of the television ââ¬Ëcaughtââ¬â¢ the contemporary audiencesââ¬â¢ eye and the African American woman represents the historically important legacy of the civil rights black movement, which is another aspect tha t appeals and relates to a modern audience.This shows that the variation in context has led to new values which Luhrmann has incorporated in his film, proving his appropriation of ââ¬ËRomeo and Julietââ¬â¢ is much more superior to Shakespeareââ¬â¢s play for a contemporary audience. A vital component and similarity in Shakespearesââ¬â¢ play and Luhrmannsââ¬â¢ film are the themes. Baz Luhrmann has kept the same themes and ideas from the original play in his film which shows they are actually timeless and can impact on all audiences, no matter what age they are a part of. One of the key themes in the play and film is love.When Romeo sees Juliet for the first time, he forgets his former love Rosaline and falls genuinely in love with Juliet. She in turn responds to him with a love that is innocent and eager. Another important theme in the two texts is hate. Peace is destroyed by the hatred that the Montagueââ¬â¢s and Capuletââ¬â¢s feel for each other and the causes o f this are not important, the results are. The love of Romeo and Juliet provides a strong contrast to the hate and are aspects of the play that do not have to be ââ¬Å"modernisedâ⬠.Hate and love can be interpreted as the duality of human life; hence even though the context of the film has differed from the play, these two themes remain to be just as relevant today as they were in Shakespeareââ¬â¢s time. Furthermore, Baz Luhrmann has taken a modern perspective on each character, giving them character traits that may have only been hinted at in Shakespearesââ¬â¢ play. An example is the different representations of Romeoââ¬â¢s first meeting with Juliet at the masked ball.In Shakespearesââ¬â¢ play, the use of language conventions such as sexual innuendo, as well as the line; ââ¬Å"And palm to palm is the holy plamersââ¬â¢ kissâ⬠portrays Juliet as either being a guarded character who is not interested in Romeo to an otherwise much more sexual and suggestive pe rsonality. On the other hand in the film, Juliet is conveyed as a flirtatious and completely exotic character. In the scene where she meets with Romeo, Luhrmann reinforces Julietââ¬â¢s sensual eye movements, with close-up shots, as she gazes past the fish in the fish tank to lock with Romeoââ¬â¢s eyes.Shakespeareââ¬â¢s characterisation of Romeo and Juliet appealed to the late 16th century audience, however as times have changed, so has the context, and Luhrmann expresses his characterisation of the couple as a way of reaching out to his young and contemporary target audience. Additionally, it is vital to remember that in the 17th and 18th centuries, plays were enacted in theatres and Shakespeareââ¬â¢s audience came to the play with a significant level of aural exposure, whereas Luhrmannsââ¬â¢ film is more visually developed. Hence, a key variation in the two text types is the techniques used.Shakespeare has expressed his ability to use diverse language to appeal to hi s audience. An example is the balcony scene of Act II Scene II, when Romeo says; ââ¬Å"It is my lady, O it is my loveâ⬠, reinforced with hyperbole ââ¬Å"two of the fairest stars in all the heavenâ⬠, exaggerating the view of Julietsââ¬â¢ sparkling eyes. Another example is Shakespearesââ¬â¢ use of puns and bawdy or sexual jokes, which can be seen in Act I Scene IV, when Romeo, Mercutio and Benvolio discuss going to the Capuletââ¬â¢s party; ââ¬Å"A torch for me! Let wantons light of heart, Tickle the senseless rushes with their heels. (Romeo jokes about the ladies at the Capulet party being immoral when they are actually respectable). An additional language feature evident is the use of similes; ââ¬Å"It seems she hangs upon the cheek of night like a rich jewel in an Ethiopââ¬â¢s earâ⬠. Romeo says this line to describe Juliet when he first sees her. The Elizabethan culture understood the puns, the sexual jokes, as well as the language that is found so anc ient and old in the 20th century. All these language conventions prove that Shakespeare wrote ââ¬ËRomeo and Julietââ¬â¢ to entertain his audience, writing within the context of his culture.On the other hand, Baz Luhrmann has adopted a style very much of his own in creating the film ââ¬ËRomeo+Julietââ¬â¢. To appeal to a contemporary audience, Luhrmann has used multiple visual techniques. One example is the use of costumes, at the Capulet ball Tybalt was dressed as a devil. This shows his evil and violent personality, representing the theme of violence and hatred. Camera work is another technique used effectively; an example is in the final scene when alternating close ups of Romeo and Julietsââ¬â¢ fingers moving are shown, which creates dramatic irony as we see Juliet waking up just as Romeo prepares to kill himself.Luhrmann also uses playful humour which can be seen when Romeo stumbles over to reach Juliet, appealing to his young audience. In addition Latin and punk m usic, a childrenââ¬â¢s choir and a production number is used in the film to create a blissful and contemporary atmosphere. It is evident, throughout the use of modern technology and visual techniques, Luhrmann has successfully made his appropriation of ââ¬ËRomeo and Julietââ¬â¢ much more superior to Shakespeareââ¬â¢s play, for a modern audience. Moreover, a variation in values between the play and film is The Wheel of Fortune and religion.During Shakespeareââ¬â¢s time, it was widely believed that fate and/or fortune was the main controlling force in life. Just as a part of a wheel moves from a low to a high position or from high to low, so does a manââ¬â¢s life. Hence, Shakespeare used this value to portray the idea of as to what extent fate and to what extent human foolishness and error, contributed to the final tragedy. On the other hand, Luhrmann takes what implications of religion there are in the play and makes them a key visual focus in his film.Romeo and Jul iet have a relationship that is based around the church, and there is usually a cross or other religious symbol in the scenes in which they appear, encouraging the story to be viewed in a Christian context. Luhrmann uses his Christ imagery as a way to show contemporary audiences that the young lovers play a Christ-like role in their families ââ¬â sacrificing themselves for the final peace between their families. Because of the loverââ¬â¢s sacrifice, Verona has hope for life, just as Christians in the world have hope for life because of their Saviour (God).Hence, Luhrmannsââ¬â¢ ââ¬ËRomeo+Julietââ¬â¢ conveys the values of its original context whilst relating to his modern audience by depicting current social issues which make it more relevant and comprehensible to the audience. Furthermore, as the context of ââ¬ËRomeo and Julietââ¬â¢ by Shakespeare has changed, so has peoplesââ¬â¢ interpretations of the play. Early psychoanalytic critics saw the complication o f ââ¬ËRomeo and Julietââ¬â¢ in terms of Romeoââ¬â¢s overconfidence developing from ââ¬Å"ill-controlled, partially disguised aggressionâ⬠, which led to Mercutioââ¬â¢s death and the lovers suicide.In the late 1900ââ¬â¢s, critics such as Julia Kristeva focused on the hatred between the Capulets and Montagues, arguing that this hatred caused Romeo and Julietââ¬â¢s passion for each other. Juliet for example, speaks of ââ¬Å"my only love sprung from my only hateâ⬠and usually articulates her love through an anticipation of Romeoââ¬â¢s death. Feminist literary critics debate that the blame for the family feud lies in Veronaââ¬â¢s patriarchal society. For example, Coppelia Kahn, a feminist critic believes the firm, manlike code of violence implied on Romeo, is the main force driving the tragedy to its end.In this view, the teenagers ââ¬Å"become menâ⬠by involving themselves in violence on behalf of their fathers. Juliet also obeys a female code of purity and obedience and she demonstrates this by allowing others, such as the Friar to solve her problems for her. This shows that ââ¬ËRomeo and Julietââ¬â¢ has had many different readings over the years and criticsââ¬â¢ values, professions and cultures can have a major influence on their interpretations. In addition, Luhrmannsââ¬â¢ ââ¬ËRomeo and Julietââ¬â¢ is not the only appropriation of Shakespearesââ¬â¢ play. The play has been adapted numerous times for stage, film, musical and opera.David Garrickââ¬â¢s 18th century version modified many scenes, removing material then thought of as offensive, and Georg Bendaââ¬â¢s adaption excluded much of the action and added a happy ending. Performances in the 19th century, such as Charlotte Cushmanââ¬â¢s, updated the original text, and centred on greater realism. In 1935, John Gielgudââ¬â¢s version reinforced the Elizabethan culture and costumes, and kept very close to Shakespeareââ¬â¢s text. In the 20th century, the play has been diversely adapted, including the 1950ââ¬â¢s musical ââ¬ËWest Side Storyââ¬â¢ and the 1996ââ¬â¢s MTV-inspired ââ¬ËRomeo and Julietââ¬â¢.It is evident that Shakespeares play ââ¬ËRomeo and Julietââ¬â¢ has a timeless storyline as well as powerful themes and language, and has been appropriated multiple times as the text is highly valued. In conclusion, it is now clear that William Shakespeareââ¬â¢s ââ¬ËRomeo and Julietââ¬â¢ is highly valued and Baz Luhrmann has taken what is valued about the original play; the themes, evocative language and poetry, the timeless storyline and humour, and has placed it in a context which is accessible and appealing to a contemporary audience.The variations in the reactions to the text over time, differences and similarities between language, settings, prologue and chorus, themes, characterisation, techniques, values and contexts, as well as different readings of the play and other appropriations has shown how and why the text has been appropriated and remains immensely valued. It is through appropriations like Luhrmannââ¬â¢s, which have continually rekindled the fire to enable the original storyline of ââ¬ËRomeo and Julietââ¬â¢ to be perceived by an ever changing audience.

Preparation of Cyclohexanol
Introduction: Cyclohexanol is mainly used in the production of caprolactam and adipic acid that is a raw material of nylon 6 (Zhang, et al, 2002). Cyclohexanol can be produce through several methods, which include the oxidation of cyclohexane, the hydration of cyclohexene, or the hydrogenation of phenol (Zhang, et al, 2002). Problem with oxidation of cyclohexene is poor selectivity, extremely large recycles and explosion hazards. (Suresh, Sridhar, Potter, 1988). The purpose of this experiment was to synthesis cyclohexanol by hydration of cyclohexene using concentrated sulphuric acid as an acidic catalyst.In hydration reaction, C=C B bond is replaced by hydroxyl group (Hornback, 2006). Overall reaction: (McFadden, 2012) In the first step, the mixture of water, concentrated sulphuric acid, and cyclohexene was shaken vigorously until it became a homogenous solution. Followed by, the addition of water, and the distillation process lead to the hydrolysis of the alkene. Finally, addition o f diethyl ether to the mixture then distillation took place to be purified and to obtain the final product, cyclohexanol (McFadden, 2012).Diethyl ether was used to extract alcohol from salt-water mixture because diethyl ethers solubility in water is lower than cyclohexanol which helps remove alcohol from the salt-water mixture (Merzougui, A, et al. , 2011). (McFadden, 2012) Cyclohexene is added to water-acid solution, which formed two liquid phases were due to insolubility of cyclohexene in water-acid solution. It is very important that mixture is mixed well to make a homogeneous solution and allow reaction to complete. Cyclohexene was reacted with water and with sulfuric acid to form protonated cyclohexanol and cyclohexyl hydrogen sulfate.Protonated cyclohexanol and cyclohexyl hydrogen sulfate are soluble in water-acid solution (McFadden, 2012). When this mixture is heated, cyclohexyl hydrogen sulfate converts to protonated cyclohexanol which is equilibrium with cyclohexanol (McFad den, 2012). Moreover, distillation technique is used to separate components of a liquid mixture, where liquid is boiled to vaporize and then condensed back into liquid called distillate. Distillate components are collected with a lowest-boiling point to highest-boiling point.In this experiment, distillation is used to separate the organic compound from sulphuric acid solution; azeotrope of cyclohexanol and water is formed as distillate, it also contains some cyclohexene components. Azeotrope has a fix boiling point like a pure compound. Cyclohexanol is considerably soluble in water, so poor yield is expected (McFadden, 2012). Addition of sodium chloride to distillate solution improves the final product yield because it reduces the solubility of organic compound, and extracts cyclohexanol from aqueous phase. It is due to saltââ¬â¢s higher solubility than organic compound.Also, anhydrous potassium carbonate is used to absorb water and to neutralize any trace of acid. During distill ation of pure cyclohexanol, most of the product should be collected as temperature reaches 161? C (Weast, 1988). This experiment also introduces determination of the refractive index; it is one of the most convenient methods used to determine purity of liquid. It is a ratio of the sine of the angle formed when light ray is bent when passing from an air medium into a liquid medium; in other words it is a ratios of the speed of light in a vacuum to the speed of light in the liquid medium.Refrective index (n) = C_vaccume/V_medium (McFadden, 2012). At 20à °C, the expected refractive index of cyclohexanol is 1. 4641 (Weast, 1988). Procedure: The experiment was done in two parts. Part-A was hydration of the alkene, and Part-B was isolation and purification of the cyclohexanol. To perform hydration of alkene, 7. 0mL of water and then 14mL of concentrated sulphuric acid were added to a 125mL Erlenmeyer flask. After that, flask was placed in ice-bath until it was cold to touch. 16. 4g of cy clohexene was added to weighed 250mL round-bottom flask.In the same round-bottom flask, the chilled water-acid mixture was added. In order to mix the solution, the flask was vigorously shaken for 20 minutes. While shaking, regularly stopper was released to prevent any build-up of vapour pressure. After flask was vented and allowed it to stand without disturbing for about 5 minutes. Because two distinct layers appeared, continued shaking for extra 10 minutes until solution was homogeneous. Next, an additional 120mL of distilled water were added in homogeneous solution with addition of 3 boiling chips.The same round-bottom flask was then set onto a distillation apparatus, and started distillation. Distillate was collected into an 125mL Erlenmeyer flask, and boiling point range of azeotrope was noted. Subsequently, 25g NaCl was dissolved to the distillate, but not all salt was dissolved. After that, flask was covered with parafilm (McFadden, 2012). In the next lab, distillate mixture w as transferred to a separatory funnel. Distillation receiver flask was washed by 20mL diethyl ether, that diethyl ether was then transferred into the separatory funnel.Mixture was allowed to delayer for 3 minutes. Afterwards, bottom aqueous layer was drained into a aqueous waste beaker; and top ether layer was transferred in an another 50mL Erlenmeyer flask which contained 3g of anhydrous potassium carbonate, swirled and allowed the mixture to stand for 15 minutes. Next, no potassium carbonate but only liquid mixture was transferred to round-bottom flask for the distillation. Diethyl ether and cyclohexene were distilled and collected into a flask until it reached 120à °C, and later discarded in an organic waste.As temperature reached 120à °C, a clean, dry and pre-weighed flask was replaced to collect final product, cyclohexanol. As soon as flask was replaced, cold water was turned-off and hot water was turned on. Continued to distil until there was no liquid in the distillation fl ask, and boiling chips started to change colour. Small amount of residue was kept in distillation flask to prevent it from breaking. Finally, cyclohexanol was weighted and from small sample the refractive index was determined (McFadden, 2012). Result: Amount of cyclohexene used = 16. 40g = 16. 40g of C_6 H_10? 1/(82. 143 g/mol)=0. 9965=0. 1997mol of C_6 H_10 Limiting reagent is: Cyclohexene Bp range of azeotrope mixture: 85-95. 4à °C Literature bp range of azeotrope mixture: 97. 8à °C; edition: 53rd; page: D-16 Bp range of diethyl ether: 34. 6-41. 6à °CLiterature bp range of diethyl ether: 34. 51à °C; edition: 53rd; page: Bp range of cyclohexene: 82. 8-90à °C Literature bp range of cyclohexene: 82-98à °C; edition: 53rd; page: C-259 Bp range of pure cyclohexanol: 157-161. 0à °C Literature bp range of cyclohexanol: 161. 1à °C; edition: 53rd; page: C-257 Weight of pure cyclohexanol = 7. 1g Percent yield = (actual yield (g))/(theoretical yield (g))? 00%=7. 1g/20. 00g? 100%=35. 5 % Theoretical yield= (0. 1997mol of C_6 H_10)/?

In this experiment, cyclohexene was hydrated to produce cyclohexanol; because the direct hydration of cyclohexene is very slow, concentrated sulphuric acid as an acidic catalyst is used to speed up the reaction (McFadden, 2012). When cyclohexene was reacted with water and concentrated sulphuric acid, da rk homogenous solution was formed from colourless heterogeneous mixture. The reaction was cyclohexene ? protonated cyclohexanol + cyclohexyl hydrogen sulfate. Both of hese products were soluble in water-acid solution, therefore reaction could go to completion (McFadden, 2012). Moreover, azeotrope of cyclohexanol and water was a positive azeotrope which means boiling point of azeotrope was less than the boiling point of cyclohexanol and water. Moreover, distillation process can prevent side reactions and by removing the products it shifts equilibrium on right hand side to increase percent yield; however, it is not enough to improve percent yield. Cyclohexanol is soluble in water; so addition of NaCl forces cyclohexanol to leave aqueous phase into organic phase.By reducing its solubility in water, NaCl molecules were holding water molecules. It is due to NaClââ¬â¢s stronger attraction to water than cyclohexanol; solubility of NaCl in water is 360g/L, and solubility of cyclohexanol in water is 36. 0g/L (Weast, 1988). It is a great way to separate azeotrope into different components. However, enough salt is necessary to make solution saturated to separate all cyclohexanol from aqueous solution; for example, 45. 72g of NaCl is needed to make solution saturated in 127mL of water. Required salt can be calculated by multiplying solubility of salt in water with given volume.In part B, there was cyclohexanol found in the condenser because temperature of water running in the condenser was low compare to melting point of cyclohexanol, which is 24à °C; so some of the cyclohexanol was stuck on the inner-surface of the condenser. Cold-water was turned off, and hot-water turned on when cyclohexanol was collecting during distillation process to remove the cyclohexanol from the surface of condenser and used in the final product. The result shows that the percent yield is 35. 5%. As expected percent yield is low because the strong acidic conditions and solubility of cyclohex anol in water (Hornback, 2006).Observed reflective index is very close to literature value of reflective index of cyclohexanol, which tells that product is pure but there is still some impurities. The result is also due to inefficient experiment procedures. This experiment required precise measurements of data in order to obtain accurate results. But, there are many possible sources of experimental error when performing this experiment. Firstly, if water-acid solution was not cooled enough to add cyclohexene, then some of the cyclohexene have evaporated.Cyclohexene is a limiting reagent meaning it will affect the overall weight of cyclohexanol by reducing the amount. Secondly, not using properly clean and dried equipments may affect on reactantsââ¬â¢ activities, such as a flask, beaker, graduated cylinders. Thirdly, solution was not homogeneous; in other words, failing to mix properly for the reaction to go to completion. It was hard to judge due to very dark colour of the soluti on. If reaction was not fully reacted means not all cyclohexene were reacted to form protonated cyclohexanol and cyclohexyl hydrogen sulfate.Fourthly, some potassium carbonate may have entered in distillation flask which resulted in reverse reaction causing to lose more cyclohexanol. Fifthly, a small amount of product might be lost when transferring from one container to another. Sixthly, some cyclohexanol was left in round-bottom flask in order to prevent the round-bottom flask from breaking due to over-drying or over-heating. There are a few methods that would improve the accuracy of the experiments, if considered and followed with care. While recording the volume from the graduated cylinder the goal is to look for at the curve on the top of a standing body of liquid.Before experiment takes place make sure to clean all equipments that are going to be used throughout experiment to avoid any beside reactions in the experiment that may affect the final result. When transferring from one flask to other, sometimes filter paper would be a better solution to prevent unwanted product from entering into a reaction flask, and to prevent any reverse reaction to occur, such as potassium carbonate. Conclusion: In this paper, distillation process for the indirect hydration of cyclohexene to cyclohexanol using sulphuric acid as an acidic catalyst is demonstrated.In the hydration process, double bond of cyclohexene is replaced by the hydroxyl group to form alcohol. Obtain reflective index of cyclohexanol is 1. 4648, and the literature value of reflective index of cyclohexanol is 1. 4641at 20à °C; which shows that final product was very pure. The result also showed that the percent yield is only 35. 5%, it is due to the strongly acidic conditions and solubility of cyclohexanol.

Field Observation of Middle School
Field observations of Middle School The favoritism, all once we have heard about the favoritism, but what exactly is? favoritism is defined as the inclination to favor more to some people than to others without assessing their merit or what is right. This is one of the most controversial topics in the institutes, elementary schools, universities, jobs even in the same family.There are several reasons why the favoritism is given, one is for the money, almost always see them as people with a good economic status can do what they want, from government up to schools, another reason may be the physical, that almost always occurs in women, among other things. In any of these cases can be harmful both to which is favored for which it is not, since helping one person, we do that does not strive for what they want and create for all are perfect, otherwise, low self esteem and it is to convince the person that it is useless.In the case of the school, I think we have all noticed or suspected th at there is some kind of favoritism of some teachers towards students, Millers teacher arenââ¬â¢t the exception in this case; never criticizing them, say that everything they do is good, or simply do nothing and still passed with very good rating.In these cases the damage affects the student who is favored since their performance is not brought to a limit or a high level of effort to gather the requirements of pass in already is a matter or more. Leading the favored student to create an atmosphere of comfort to her around and so accustomed to not avail themselves of their merits to get something in daily life. On the contrary, the student who is not favored, as I mentioned before, tends to have low self-esteem and even strives to be better.In my fifth time tutoring at Miller, I notice a little unusual, that many teachers probably doesnââ¬â¢t pay attention or they do it without realizing they are doing it, which was having one of the girls as her favorite student, she was pay m ore attention to this student, she was trying to talk to her more softly, and this student was as we can call it the right hand of the teacher. I am not opposed students being more helpful, but the problem is when students are being more control and yelled at any situation.The favoritism is evident in this situation. Today there was another incident at school, when we arrived at Miller, there was a teacher with male student, the teacher was furious and was demanding to call the police, and we were there for part of this whole situation waiting our turn to sing in. The teacher was screaming and angry at this student because the teacher forgot her bag in the classroom.When she returned to her classroom, she said there was missing her credit card, driver license, and social secure number card, I know some of these documents are very important for any individual, but when the teacher returned to class there was only a single students in classroom, and because he is male and most likely easy to get in trouble was blame for this indecent. I am not saying that this student was innocent, why blame only the last male student that was in class? Why not the whole classroom?Is it because maybe the teacher thinks that a girl student was incapable of stealing those important documents from her teacher; or is it easier to presume that it was a male student who stole those documents from her. I left the office before the whole indecent was fixed, I am not even shore if the teacher brought all of those documents she was saying was stolen from her gab, because when an instructor has to teach more than 30 students a day plus they have to do parenting at home as well, the responsibility becomes greater because of these a person do make mistakes as well, like forgetting those documents at home.
