Question

How would you convert Aniline to Chlorobenzene?

Answer 1

Conversion of Aniline to Chlorobenzene:-

Step 1: Formation of Diazonium salt

When the Aniline is tested with Sodium nitride and Hydrochloric acid, at a temperature between $(0-4)°\mathrm{C}$ produces Diazonium salt of Benzene

Step 2: Formation of Chlorobenzene

This diazonium salt formed then is reacted with ${\mathrm{Cu}}_2{\mathrm{Cl}}_2$and Hydrochloric acid to undergo Sandmeyer reaction and produce Chlorobenzene:

This conversion of Aniline to Chlorobenzene is a 2 step reaction.
