A) \[R-\overset{\begin{smallmatrix} O \\ || \end{smallmatrix}}{\mathop{C}}\,-Cl~~~\]
B) \[RCONHC{{H}_{3}}\]
C) \[RCON{{H}_{2}}\]
D) \[RCOOR\]
Correct Answer: C
Solution :
Hofmann Reaction: In this reaction acid amide group reacts with \[B{{r}_{2}}\] in presence of \[NaOH\] or KOH to give primary amine group. The amine is one carbon less than the parent amide. So, the reaction is known as Hofmann degradation reaction. \[\underset{Acid\text{ }amide}{\mathop{R-CON{{H}_{2}}}}\,+B{{r}_{2}}+4KOH\xrightarrow{\Delta }\] \[\underset{Primary\text{ }amine}{\mathop{RN{{H}_{2}}}}\,+2KBr+{{K}_{2}}C{{O}_{3}}+2{{H}_{2}}O\]You need to login to perform this action.
