The method by which aniline cannot be prepared is

Question

The method by which aniline cannot be prepared is (A) Nitration of benzene followed by reduction with Sn and con HCI (B) Degradation of benzamide with bromine in alkaline solution (C) Reduction of nitrobenzene with H2 / Pd is ethanol (D) Potassium salt of phthalimide treated with chlorgbenzene followed by the hydrolysis with aqueous NaOH solution

Tardigrade Admin · Accepted Answer

Gabriel phthalimide synthesis not preferred for preparing aniline because amine formation involves nucleophilic substitution of alkyl halides by the anion formed by phthalimide. But aryl halides do not undergo nucleophilic substitution.
