Synthesis of 1-Bromobutane - 3057 Words

November 15, 2007 Synthesis of 1-Bromobutane Introduction: The purpose of this experiment is to synthesize 1-bromobutane from 1-butanol and sodium bromide. In order for this reaction to reach completion there are four major operations that need to be performed. The four major operations include refluxing, simple distillation, separation, and drying. To begin, in order for the compounds to react they will be dissolved in water and sulfuric acid will be added. The addition of sulfuric acid will then generate hydrobromic acid, an important product in the reaction mixture. The hydrobromic acid will react with the 1-butanol when heat is added to the flask during refluxing. Refluxing is the heating of a flask to boiling and then allowing†¦show more content†¦Reaction Mechanism: NaBr, H2SO4 CH3CH2CH2CH2OH CH3CH2CH2CH2Br + NaHSO4 + H2O (1-Butanol) (1-Bromobutane) Flowchart: -Reflux for 30 minutes -Perform Simple Distillation -Simple Distillation -Infrared Spectroscopy Observations: • After adding sulfuric acid to the mixture of NaBr, 1-butanol, and water there was a brief yellow stream that appeared and then became clear. • After adding all four reactants and keeping the mixture cold a cloudy, white residue was present in the bottom of the flask. • A cold, wet pipe cleaner was then added to the top of the reaction flask to keep the column cold which caused no vapors to rise into the column. • When the heat was added to the flask the residue dissolved and the reactant mixture was clear. • Before boiling commenced two layers formed in the reaction flask. The bottom layer was slightly cloudier than the clear top layer. • As the mixture boiled the vapors rose slightly into the bottom ofShow MoreRelatedSynthesis of 1- Bromobutane an Sn2 Reaction1160 Words   |  5 PagesExperiment 13: Synthesis of 1- Bromobutane An SN2 Reaction Theory: One of the methods of preparing alkyl halides is via the nucleophilic substitution reactions of alcohols.

Rhetorical Devices in Great Gatsby Free Essays

Gatsby Essay Honors English II Asura Louise Osborne In the 1920’s, the world was full of new inventions, dances, and drinks. The standards of even the most rigorously structured social classes were changed, allowing the rich to cut loose and throw elaborate and entertaining parties. Every day, the world was changing for the better. We will write a custom essay sample on Rhetorical Devices in Great Gatsby or any similar topic only for you Order Now Author F. Scott Fitzgerald’s work â€Å"The Great Gatsby† reflects these ideas, communicating through various rhetorical devices that the world is a magical place, and that even in times of sadness, anything is possible. Prior to the Jazz Age, growing up was associated with a loss of happiness and hope. During the 20’s, however, this standard seemed to change, pushing the perception of adulthood into something magical and frivolous. Fitzgerald reflects this in the archetypal portrayal of a city, describing it as â€Å"in white heaps and sugar lumps†. White is an archetype for purity, innocence, and hope. It illuminates the hope that the young adults living in the 1920’s felt, as well as the innocent parties they danced at, innocent not because of what took place in them, but because they were blissfully unaware of the harsh realities that existed elsewhere in the world. Happiness is also communicated in the use of the word â€Å"sunlight†, because the sun is an archetype for energy and hope. Through the personification of the city â€Å"rising up†, it is illuminated that the roaring twenties came from seemingly nowhere, almost like a fairytale. The magic of the upper classes’ world was also portrayed in the hyperbole, â€Å"all built with a wish. † In reality, the city merely began as a wish, but Fitzgerald portrays it as something that sprung up from a thought. Potentially the most illuminatory literary device is the imagery in the sentence â€Å"its wild promise of all the mystery and the beauty in the world. † The picture painted is one of excitement, hope, and perhaps most importantly, the creation of a wonderful world borne from fancy. In times of loss, a traditional coping mechanism is bargaining. This is generally portrayed as â€Å"If I do such and such, so and so will come back. † It is usually a time when the bargainer believes in part that anything is possible. F. Scott Fitzgerald dives into that idea when Jay and Nick become part of a funeral procession. One way he communicates the idea that anything is possible is in the juxtaposition of life and death, â€Å"A dead man†¦in a hearse†¦heaped with blooms†¦Ã¢â‚¬  His diction also illuminates this concept through the use of the word â€Å"blinds†, suggesting that most people are blind to the presence of possibility. In addition to diction and juxtaposition, Nick’s reaction to seeing blacks in an affluent setting also illuminates that Fitzgerald is communicating through him, â€Å"Anything can happen now†¦anything at all. † Even in the presence of a â€Å"somber holiday†, the world is still coming up with new possibilities. The world is ever changing, which is one thing that makes life on Earth so exciting. All of the changes that are present today really began in the 1920’s though, a time of new ideas and hopes. F. Scott Fitzgerald led America’s run head-first into the Jazz Age, and gave future generations a peek inside what life was like at the time with his novels. In his book, â€Å"The Great Gatsby†, he uses many literary devices to illuminate the concepts that life is magical, and that even in times of sadness, the world is filling itself with new possibilities.
