Vedclass · Answer

(C) The Hofmann bromamide degradation reaction is a characteristic reaction of primary amides.In this reaction,a primary amide $(R-CONH_2)$ reacts with bromine $(Br_2)$ in the presence of a strong base like potassium hydroxide $(KOH)$ to form a primary amine $(R-NH_2)$ with one carbon atom less than the original amide.The balanced chemical equation is:$R-CONH_2 + Br_2 + 4KOH \xrightarrow{} R-NH_2 + 2KBr + K_2CO_3 + 2H_2O$Therefore,the compound that undergoes this reaction is $R-CONH_2$.

Indicate which nitrogen compound amongst the following would undergo Hofmann's reaction (i.e.,reaction with $Br_2$ and strong $KOH$) to furnish the primary amine $(R-NH_2)$.
