Question

Complete the following reactions:
$C_6{H}_5-{CONH}_2\stackrel{{Br}_2/KOH}{\to }A\underset{{CHCl}_3}{\overset{KOH}{\to }}B\underset{Sn/HCl}{\overset{}{\to }}C$

Answer 1

(Refer to Image)

When amide reacts with $B{r}_2$ in presence of $KOH$, an amine is formed with and the product has one carbon less than the parent substrate, it is called Hoffmann bromamide reaction and when aniline (a primary amine) is made to react with $KOH/CHC{l}_3$, a carbylamine is formed. $Sn/HCl$ is used for the reduction of many carbon compounds.
