Question

How do you convert aniline to chlorobenzene and name the reaction

Answer 1

The process of conversion of Aniline to Chlorobenzene takes place in two step as follows:

a. Sodium nitrite and hydrochloric acid is added to Aniline at very low temperatures ( 0–4ºC) to form a benzene diazonium ion (a diazonium salt).  

b. This diazonium salt in presence of leftover hydrochloric acid is further treated with Copper Chloride which forms Chlorobenzene.

Chlorobenzene is used to manufacture various organic chemicals and is also used as an adhesive solvent.
