In the reaction of phenol with CHCl₃ and aq.KOH the electrophile attacking the ring is
Options
(a) CHCl₃
(b) CHCl₂
(c) :CCl₂
(d) COCl₂
Correct Answer:
:CCl₂
Explanation:
The electrophile is dichloromethylene :CCl₂ generated from chloroform by the action of a base. OH⁻ + CHCl₃ ⇌ HOH + :CCl₃ → Cl⁻ + :CCl₂(Dichlorocarbene).
