Question
Give reasons for the following observation:
Aniline is acetylated before nitration reaction.

Solution
Aniline is acetylated, before the nitration reaction in order to avoid the formation of tarry oxidation products and protect the amino group, so that p-nitro derivative can be obtained as major product.
