When phenol is allowed to react with `Br_(2)` in (i) `CS_(2)` solution and (ii) in aqueous solution, the resulting compounds are

Options

A. (i) `2,4,6-`tribromophenol and
(ii) `o-`and `p`-bromophenol
B. (i) `m-`bromomphenol and
(ii) `2,3,4-`tribromophenol
C. (i) `o-`and `p`-bromophenol and
(ii) `2,4,6-`tribromophenol
D. (i) `o`-and `m-`bromophenol and
(ii) `2,3,4-`tribromophenol

Answer

C

Explanation

In aq. Solution phenol ionizes to give phenoxide in which highly activates benzene ring and give trisubstituted product while in presence of `CS_(2)` an intert solvant phenol is unable to ionize due to which benzene ring in slightly activated. Hence, monosubstituted product is obtained.
