Question

An aromatic compound 'A' on heating with $B r_{2}$ and $K O H$ forms a compound 'B' of molecular formula $C_{6} H_{7} N$ which on reacting with $C H C l_{3}$ and alcoholic $K O H$ produces a foul smelling compound 'C'. Write the structures and IUPAC names of compounds A,B and C .

Solution

When benzamide reacts with $B r_{2} / K O H$ Hoffmann bromamide degradation reaction will take place to form aniline and when aniline is treated with $C H C l_{3} / K O H$ carbylamine reaction will take place to form phenyl isocyanide
$∴$ $A : B e n z a m i d e$
$B : A n i l i n e$
$B : P h e n y l i s o c y n a i d e$
