Nitrogen Containing Compounds Question 3
Question: Indicate which nitrogen compound amongst the following would undergo Hofmann’s reaction (i.e. reaction with $ Br_2 $ and strong KOH) to furnish the primary amine ( $ R-NH_2 $ ) [CBSE PMT 1989]
Options:
A) $ R-\overset{O}{\mathop{\overset{||}{\mathop{C}},}},-NH.CH_3 $
B) $ R-\overset{O}{\mathop{\overset{||}{\mathop{C}},}},-O.NH_4 $
C) $ R-\overset{O}{\mathop{\overset{||}{\mathop{C}},}},-NH_2 $
D) $ R-\overset{O}{\mathop{\overset{||}{\mathop{C}},}},-NHOH $

Answer:
Correct Answer: C
Solution:
Hofmann degradation of amide $ R-CoNH_2+Br_2+4KOH\xrightarrow{{}} $ $ \underset{\text{primary amine}}{\mathop{R-NH_2}},+2KBr+K_2CO_3+2H_2O $
