Vedclass · Answer

(A) The reaction described is the Hofmann bromamide degradation reaction.In this reaction,an amide is treated with bromine $(Br_{2})$ and an aqueous solution of a strong base like potassium hydroxide $(KOH)$ to produce a primary amine.The reaction is as follows:$R-CONH_{2} + Br_{2} + 4KOH \rightarrow R-NH_{2} + K_{2}CO_{3} + 2KBr + 2H_{2}O$This reaction is used to decrease the carbon chain length by one carbon atom,which is removed as a carbonate ion $(CO_{3}^{2-})$.

Which one of the following reagents is used to obtain an amine by heating it with an amide?
