Key Idea The reagent which can convert −CONH2 group into −NH2 group is used for this reaction. Among the given reagents only NaOH/Br2 converts −CONH2 group to −NH2 group, thus it is used for converting acetamide to methyl amine. This reaction is called Hofmann bromamide reaction. acetamide CH3CONH2+NaOH+Br2⟶CH3NH2 methyl amine +NaBr+Na2CO3+H2O
