Vedclass · Answer

(C) The reaction of an amide with $[KOH + Br_2]$ is known as the $Hofmann$ bromamide degradation reaction. In this reaction,the amide is converted into a primary amine with one carbon atom less than the original amide. To obtain ethanamine $(CH_3CH_2NH_2)$,which has $2$ carbon atoms,the starting amide must be propanamide $(CH_3CH_2CONH_2)$. However,looking at the options provided,ethanamide $(CH_3CONH_2)$ would yield methanamine $(CH_3NH_2)$. Since the question asks for ethanamine,none of the options are strictly correct based on the standard degradation product. However,if we consider the transformation of $CH_3CH_2CONH_2$ (propanamide) to ethanamine,it is the standard application. Given the options,if the question implies the product of the reaction of the given amides,ethanamide gives methanamine,and propionamide gives ethanamine. Therefore,propionamide is the correct precursor for ethanamine.
