Q. Chlorination of benzene is not possible in the following reaction
A) $C_{6}H_{6} + Cl_{2}\overset{FeCl_{3}}{\rightarrow}$
B) $C_{6}H_{6} + HOCl\overset{H^{+}\ \ \ }{\rightarrow}$
C) $C_{6}H_{6} + I - Cl\overset{ZnCl_{2}\ \ \ }{\rightarrow}$
D) $C_{6}H_{6} + Cl_{2}\overset{AlCl_{3}\ \ \ \ }{\rightarrow}$
Explanation
(b)
Benzene undergoes electrophilic substitution in presence of $AlCl_{3}\ or\ FeCl_{3}\ or\ ZnCl_{2}$.
Benzene does not undergo addition reactions like alkene.
$\therefore$ $C_{6}H_{6} + HOCl\overset{H^{+}}{\rightarrow}$no product and (b) is correct answer.
