प्रश्न
Aniline does not give Friedel-Crafts reaction. Give a reason.

उत्तर
Aniline does not undergo Friedel-Craft's reaction because the reaction takes place in the presence of AlCl3, but AlCl3 is a Lewis acid, whereas aniline is a strong basic. Thus, aniline interacts with AlCl3 to produce a salt.
The positive charge on the N-atom prevents electrophilic substitution in the benzene ring. As a result, aniline does not undergo the Friedel-Craft reaction.
