Show Answer

Answer (1)

Solution

The $NH _2$ group in Aniline is ortho and para directing and a powerful activating group as $NH _2$ has strong $+M$ effect.

Aniline does not undergo Friedel-Craft’s reaction (alkylation and acylation) as Aniline will form complex with $AlCl _3$ which will deactivate the benzene ring.
