Which of the following pairs of amines can be successfully prepared using Gabriel phthalimide synthesis?

Step-by-step solution

Gabriel phthalimide synthesis is exclusively used for the preparation of primary aliphatic amines. It cannot be used to prepare primary aromatic amines because aryl halides do not undergo nucleophilic substitution with the phthalimide anion. It is also not applicable for the preparation of secondary or tertiary amines. Aniline and p -toluidine are primary aromatic amines, hence they cannot be prepared by this method. N-Methylethanamine is a secondary amine and N,N-Dimethylamine is a tertiary amine, so they cannot b
