1. Aniline is basic, and acetanilide is not basic. Explain this difference. 2. If 10 g of aniline react with an excess of acetic anhydride, what is the theoretical yield of acetanilide in moles, in grams? 3. Write the equations for the reaction of aniline with acetyl chloride and with acetic acid to produce acetanilide. In the introduction to this experiment, the hydrolysis of acetic anhydride is mentioned as a competitive reaction. 4. Write an equation for this reaction. 5. Give two reasons why the crude product in many reactions is not pure.
