13.10 An aromatic compound ‘A’ on treatment with aqueous ammonia and heating forms compound ‘B’ which on heating with $Br_{2}$ and $KOH$ forms a compound ‘C’ of molecular formula $C_{6}H_{7}N.$ . Write the structures and IUPAC names of compounds A, B and C.

The molecular formula of C = $C_{6}H_{7}N$

$A\xrightarrow[aq NH_{3}]{\Delta }B$

$B+Br_{2}+KOH\rightarrow C(C_{6}H_{7}N)$ it is a Hoffmann bromamide degradation reaction so, the product should be $C_{6}H_{5}NH_{2}$ (aniline)

So B should be benzamide ( $C_{6}H_{5}CONH_{2}$ ) and A should be benzoic acid ( $C_{6}H_{5}COOH$ )

Therefore the above reaction proceeds as-
