Our data displayed supports the notion that by increasing the acidity of the catalyst‚ the production of aspirin will increase. Our hypothesis was proven correct. In our data‚ we calculated the percent yield and percent error of each trial. We also calculated the average of the percent yields and the percent errors of each catalyst. In the end‚ we saw that for the sulphuric acid catalyzed aspirin‚ we saw an average of 69.7% percent yield and an average 30.3% percent error. As for the phosphoric acid

Preparation of 4-bromoaniline Introduction Aromatic compounds tend to undergo electrophilic aromatic substitutions rather than addition reactions. Substitution of a new group for a hydrogen atom takes place via a resonance-stabilized carbocation. As the benzene ring is quite electron-rich‚ it almost always behaves as a nucleophile in a reaction which means the substitution on benzene occurs by the addition of an electrophile. Substituted benzenes tend to react at predictable positions. Alkyl groups

Lab 3: Grignard Synthesis Objective: The goal of this lab is to synthesize a Grignard reagent from bromobenzene and magnesium metal in diethyl ether. This same Grignard reagent would then be used to prepare a tertiary alcohol and then purify and characterize the product.

aryl-magnesium halide. The nucleophilic Grignard reagent attacks an electrophilic carbon‚ which results in the formation of a carbon-carbon bond. Forming carbon-carbon bonds are very synthetically useful. The electrophilic carbons found within a carbonyl group are the most likely to be attacked because of their polarity. The Grignard reagent is formed by the reactions between an alkyl or aryl-halide and magnesium. The reaction proceeds via a radical electron transfer. Iodine can also be added
