MCQ

An aromatic compound '$A$' on treatement with aqueous ammonia and heating forms compound '$B$' which on heating with $Br_2$ and $KOH$ form a compound $C$ of molecular formula $C_6H_7N$. The structures of compound $A, \,B$ and $C$ are respectively

A
$C_6H_5CH_3$, $C_6H_5CONH_2.C_6H_5CH_2NH_2$
B
$C_6H_5CHO$, $C_6H_5CONHCH_3$, $C_6H_5CH_2-NH_2$
✓
$C_6H_5COOH$, $C_6H_5CONH_2$, $C_6H_5NH_2$
D
$C_6H_5COOH$, $C_6H_5NH-C_2H_5$, $C_6H_5NH_2$

✓

Answer

Correct option: C.

$C_6H_5COOH$, $C_6H_5CONH_2$, $C_6H_5NH_2$

c
${{C}_{6}}{{H}_{5}}COOH\,\xrightarrow{N{{H}_{3}}}{{C}_{6}}{{H}_{5}}COON{{H}_{4}}$ $\xrightarrow{\Delta }$

$\begin{matrix}
{{C}_{6}}{{H}_{5}}-C-N{{H}_{2}} \\
|| \\
O \\
\end{matrix}$ $\xrightarrow{B{{r}_{2}}/KOH}\,{{C}_{6}}{{H}_{5}}N{{H}_{2}}$
