$R-CONH_2$

Vedclass · Answer

(A) The Hofmann bromamide degradation reaction is specific to primary amides $(R-CONH_2)$.When a primary amide reacts with $Br_2$ and $KOH$,it undergoes rearrangement to form a primary amine $(R-NH_2)$ with one carbon atom less than the original amide.The reaction is: $R-CONH_2 + Br_2 + 4KOH \rightarrow R-NH_2 + K_2CO_3 + 2KBr + 2H_2O$.Thus,the correct compound is $R-CONH_2$.

Which of the following nitrogen compounds gives a primary amine upon reaction with $Br_2$ and strong $KOH$ (Hofmann bromamide degradation reaction)?
