Question

Give reason:
Aniline does not undergo Friedal-Crafts reaction.

Answer 1

Aniline does not undergo friedel craft reaction.

As we know aniline is weak base.

In Friedal craft reaction we use $AlC{l}_3$ as a reagent along with alkyl/arylhalides.

$AlC{l}_3$ is lewis acid.

When we add aniline to $AlC{l}_3$

So, there is acid base reaction happens and formation of salt prevents the Friedal craft reaction.
