    Abstract – This 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

    Experiment 23: Synthesis of an Alkene April 5‚ 2013 Purpose: Results and Discussion The weight of our n-Butyl Bromide sample (actual yield) was 0.09g. The percent yield was found to be 4.38%. Only 0.09g of the theoretical 2.055g yield was obtained. The boiling point was 104° C‚ which is higher than the literature value of 101° C. This is due to the sample being somewhat impure‚ as impurities tend to increase boiling point. When IR spectroscopy was performed‚ there were no OH stretches
