Write following conversions:

(i) nitrobenzene → acetanilide

(ii) acetanilide → p-nitroaniline

Class 12th Chemistry - Exemplar 13. Amines

Answer :

(i) nitrobenzene → acetanilide

Nitrobenzene is reduced to aniline in the presence of Sn/HCl. The amino group of aniline is then acetylated with acetic anhydride in the presence of pyridine.

(ii) acetanilide → p-nitroaniline

Acetanilide is allowed to react with nirating mixture to form p-Nitroacetanilide. P-nitroacetanilide is then converted to p-nitroaniline by hydrolysis.

A colourless substance ‘A’ (C6H7N) is sparingly soluble in water and gives a water soluble compound ‘B’ on treating with mineral acid. On reacting with CHCl3 and alcoholic potash ‘A’ produces an obnoxious smell due to the formation of compound ‘C’. Reaction of ‘A’ with benzenesulphonyl chloride gives compound ‘D’ which is soluble in alkali. With NaNO2 and HCl, ‘A’ forms compound ‘E’ which reacts with phenol in alkaline medium to give an orange dye ‘F’. Identify compounds ‘A’ to ‘F’.
