Vedclass · Answer

(C) The Hofmann bromamide degradation reaction is represented as: $R-CONH_2 + Br_2 + 4KOH \rightarrow R-NH_2 + K_2CO_3 + 2KBr + 2H_2O$. In this reaction,the amide group $(-CONH_2)$ is converted into an amine group $(-NH_2)$. The carbon atom of the carbonyl group is lost as potassium carbonate $(K_2CO_3)$. The loss in molar mass corresponds to the mass of the carbonyl group $(CO)$ that is removed from the amide to form the amine. The molar mass of $CO$ is $12 + 16 = 28 \ g \ mol^{-1}$. Therefore,the loss in molar mass is $28 \ g \ mol^{-1}$.
