Amine that cannot be prepared by Gabrielphthalimide synthesis is

Answer»

aniline
benzyl amine
methyl amine
iso-butylamine

Solution :Only `1^(@)` amines can be obtained by Gabriel synthesis. Aniline cannot be obtained by this method as aryl halides `(C_(6)H_(5)Cl or C_(6)H_(5)Br)` do not undergo nucleophilic SUBSTITUTION (i.e., cleavage of C-X BOND in haloarene is difficult) with potasium phthalimide under ordinary CONDITIONS to give N-phenyl phthalimide
