    The reaction \[RCON{{H}_{2}}+B{{r}_{2}}+KOH\xrightarrow{\Delta }\]gives \[1{}^\circ \]amine. The name of the reaction is

    A)  Hofmann bromamide degradation reaction

    B)  Sandmeyer reaction

    C)  Carbylamine reaction

    D)  Gattermann reaction

    Correct Answer: A

    Solution :

                    Amides on reaction with \[B{{r}_{2}}\] in an aqueous or ethanolic solution of \[NaOH\]given \[1{}^\circ \]amine with one C-atom less than that present in the amide. \[R-CON{{H}_{2}}+B{{r}_{2}}+4KOH\xrightarrow{\Delta }\]          \[\underset{1{}^\circ \,amine}{\mathop{RN{{H}_{2}}}}\,+2KBr+{{K}_{2}}C{{O}_{3}}+2{{H}_{2}}O\] This is Hofmann bromamide degradation reaction.
