Question

An organic compound (A) of molecular formula $C_{7} H_{8} O$ on treatment with lead nitrate gives a compound (B) of molecular formula $C_{7} H_{6} O$ . (B) on chlorination in presence of $F e C l_{3}$ form compound (C). Identify A, B and C, write the reactions.

Solution

$A (C_{7} H_{8} O)$ should have one phenyl ring due to such molecular formula and again it reacts with $P b {({N O}_{3})}_{2}$ to give $C_{7} H_{6} O$ . Therefore it is an oxidation reaction. So, A should be an alcohol having a phenyl ring. So the structure may be as shown in figure
