Account for the following : Aniline does not undergo Friedel-Crafts reaction.

Answer»

Solution :Aniline being a Lewis base reacts with Lewis ACID `AlCl_(3)`, which is used as a catalyst in Friedel-Crafts reaction to FORM a salt.

As a result, N of aniline ACQUIRES +ve charge and hence it ACTS a strong deactivating group for electrophilic substitution reaction. CONSEQUENTLY, aniline does not undergo Friedel-Crafts reaction.
