Vedclass · Answer

(C) The Hoffmann bromamide degradation reaction is a method used to convert a primary amide into a primary amine containing one carbon atom less than the starting amide.The general reaction is: $R-CONH_2 + Br_2 + 4KOH \rightarrow R-NH_2 + K_2CO_3 + 2KBr + 2H_2O$.Among the given options,$CH_3CONH_2$ (acetamide) is the only primary amide. The other compounds are a nitrile $(CH_3CN)$,a secondary amide $(CH_3CONHCH_3)$,and an isocyanide $(CH_3NC)$.Therefore,$CH_3CONH_2$ undergoes the Hoffmann degradation reaction.
