Lab 3: Bromination of Acetanilide CHEM 2110 Hassan Alsaleh 0525970 Due date :11/02/2015 Q1: To find the limiting reagent we need to find the number of moles of acetanilide‚ and the number of moles of Bromine. Mass of Acetanilide used = 0.67g Molar mass of Acetanilide = 135.16g/mol[1] Number of moles of Acetanilide = (0.67g) / (135.16g/mol) = 0‚005 mols Volume of Bromine = 0.25ml Density of Bromine = 3.103 g/ml[2] Mass of Bromine = (0.25ml) X (3.103g/ml) = 0.78g Molar mass of Bromine

multi-step synthesis uses aniline as the starting reagent to synthesize five compounds employing several reactions such as acetylation‚ diazo coupling‚ nitration‚ bromination‚ and hydrolysis. The isolated products were analyzed with TLC and spectral data that determined most products were pure while some had a few impurities indicated by GC‚ LC‚ and a wide melting point range was shown for products 2 and 3. The presence of water in product 2 and 7 was indicated by the IR. Acetanilide and diazoaminobenzene

Purifying Acetanilide by Recrystallization Results: Acetanillide Solubility of acetanilide in water is 5.5g/100mL at 100C 0.53g/100mL at 0C PERCENT YIELD/THEORETICAL YIELD: Discussion: Acenatilide is a synthetic organic compound introduced in therapy in 1866 as a fever-reducing drug. Its effectiveness in relieving pain was discovered soon thereafter‚ and it was used as an alternative to aspirin. The solvent that I selected to recrystallize the

Nitration of Acetanilide Introduction When organic compounds are nitrated it changes the composition and reaction of the compounds.[4] We could benefit from these changes‚ nitration of acetanilide produces a product called p- Nirtoanoline. P-Nitroaniline is commonly used as an intermediate in the synthesis of dyes‚ antioxidants‚ pharmaceuticals and gasoline. P-Nitroaniline is also used in gum inhibitors‚ poultry medicines and as a corrosion inhibitor. [2] Nitration is a type of chemical

I. INTRODUCTION Synthesis Acetylsalicylic acid is an acetyl derivative of salicylic acid which appears as a white and crystalline and a weakly acidic substance with a melting point of 135°C and is also known to be aspirin. It is one of the most widely used drugs that can lower fever and is used as a painkiller. According to (Escobel‚ 2011)‚ Aspirin is synthesized through the reaction of salicylic acid with acetyl anhydride that causes a chemical reaction that turns salicylic acid’s hydroxyl group

I found out that my family thinks that I am a responsible person in terms of sense of responsibility. But my brother thinks I’m immature. In terms of duties at home‚ my mother and father understand that I don’t perform my duties because I’m busy with my studies. My sister thinks it too but she justified that I perform when I’m not busy. When

Synthesis The idea of gender wage discrimination being widely practiced in the United States today is a difficult concept for many to swallow. With the Equal Pay Act of 1963 and Title VII of the Civil Rights Act of 1964‚ the realization of the existence of the gender wage gap surprises many Americans. These authors bring to the forefront the idea that there is more to the gender wage gap then just companies discriminating against women and minorities. They sight many sources with defined data

Synthesis “The kingdom of heaven is within the mind of a person‚ not within the collective mindlessness of a crowd.” In the articles‚ “The Only True God and Jesus Christ Whom He Hath Sent”‚ by Jeffery R. Holland and “Propaganda under a dictatorship”‚ by Aldous Huxley are two totally different topics. This paper will be a breaking down of the two articles and finding the similarities between the two of them. It will be interesting‚ but nothing is impossible. The two topics are Hitler wanting so
