Vedclass · Answer

(B) $1$. Gabriel phthalimide synthesis is used for the preparation of primary aliphatic amines.$2$. It involves the reaction of potassium phthalimide with an alkyl halide followed by alkaline hydrolysis.$3$. Aromatic amines $(C_6H_5NH_2)$ cannot be prepared by this method because aryl halides do not undergo nucleophilic substitution with the phthalimide anion.$4$. Secondary and tertiary amines cannot be prepared because the reaction requires an $S_N2$ mechanism, which is hindered by steric factors in secondary and tertiary alkyl halides.$5$. Among the options, $C_2H_5NH_2$ is a primary aliphatic amine, which can be prepared using this method.

Which of the following amines is obtained by Gabriel phthalimide synthesis?
