MCQ

Indicate which nitrogen compound amongst the following would undergo Hofmann's reaction (i.e. reaction with $B{r_2}$ and strong $KOH$) to furnish the primary amine ($R - N{H_2}$)

A
$R - \mathop {\mathop C\limits^{||} }\limits^O - NH.C{H_3}$
B
$R - \mathop {\mathop C\limits^{||} }\limits^O - O.N{H_4}$
✓
$R - \mathop {\mathop C\limits^{||} }\limits^O - N{H_2}$
D
$R - \mathop {\mathop C\limits^{||} }\limits^O - NHOH$

✓

Answer

Correct option: C.

$R - \mathop {\mathop C\limits^{||} }\limits^O - N{H_2}$

c
(c) Hofmann degradation of amide

$R-CoN{{H}_{2}}+B{{r}_{2}}+4KOH\xrightarrow{{}}$ $\mathop {R - N{H_2}}\limits_{{\text{primary amine}}} + 2KBr + {K_2}C{O_3} + 2{H_2}O$
