Aniline does not undergo Friedel-Crafts reaction because
(A) It forms salt with the Lewis acid catalyst, AlCl_3.
(B) Nitrogen of aniline acquires negative charge.
(C) Nitrogen of aniline acquires positive charge.
(D) Nitrogen acts as a strong deactivating group in the further reaction.
Choose the correct answer from the options given below :

Correct option is C

Aniline, N-substituted and N,N-disubstituted anilines do not undergo Friedel-Craft's reactions due to salt formation with aluminium chloride which is used as a Lewis acid catalyst. Positive charge on nitrogen is strongly electron-withdrawing and thus deactivates the ring for further acylation or alkylation reactions.
