Vedclass · Answer

(B) The Gabriel phthalimide synthesis is specifically used for the preparation of primary aliphatic amines. It involves the reaction of potassium phthalimide with an alkyl halide,followed by alkaline hydrolysis. It cannot be used for the preparation of aromatic amines because aryl halides do not undergo nucleophilic substitution with the phthalimide anion. It is also not suitable for secondary or tertiary amines. In the given options: $CH_3-NH-CH_3$ is a secondary amine. $(CH_3)_3C-NH_2$ is a primary amine,but it is sterically hindered and does not react well under these conditions. $C_6H_5-NH_2$ is an aromatic amine. $CH_3-CH_2-NH_2$ is a primary aliphatic amine,which is the standard product of this reaction. Therefore,the correct answer is $CH_3-CH_2-NH_2$.
