Vedclass · Answer

(D) The Hoffmann bromamide reaction requires a primary amide $(R-CONH_2)$ to react with $Br_2$ and $KOH$ to form an isocyanate intermediate,which subsequently yields a primary amine.$N$-substituted amides like $Ph-CONH-Ph$ do not possess the necessary hydrogen atoms on the nitrogen to form the isocyanate intermediate,hence they do not undergo this reaction.Therefore,the correct option is $D$.
