Questions
Answer the following.
Write a reaction to bring about the following conversions: Aniline into p-nitroaniline
Explain nitration of aniline. Write reactions for the preparation of p-nitroaniline.
Solution
Nitration: Direct nitration of aniline yields (p-nitroaniline) a mixture of ortho, meta, and para nitroanilines. In an acidic medium the -NH2 group is protonated to the -N+H3 group which is meta-directing and deactivating. Hence, a considerable amount of m-nitroaniline is obtained.
Preparation of p-nitroaniline: However, to get p-nitroaniline as a major product, the –NH2 group is first protected by acetylation and then nitration is carried followed by hydrolysis amide.
