Account for the following :
(a) Aniline is a weaker base compared to ethanamine.
(b) Aniline does not undergo Friedel-Crafts reaction.
(c) Only aliphatic primary amines can be prepared by Gabriel Phthalimide synthesis.
(a) Aniline is a weaker base compared to ethanamine because the lone pair of nitrogen in aniline is in resonance or conjugation with the benzene ring.
(b) Aniline does not undergo Friedel-Crafts reaction because Aniline forms salt with anhydrous AlCl3 .
(c) Only aliphatic primary amines can be prepared by Gabriel Phthalimide synthesis as only alkyl halides undergo nucleophilic substitution.
