Question

Given below are two statements: \ Statement I : Bromination of phenol in solvent with low polarity such as $\mathrm{CHCl}_{3}$ or $\mathrm{CS}_{2}$ requires Lewis acid catalyst.\ Statement II : The Lewis acid catalyst polarises the bromine to generate $\mathrm{Br}^{+}$.\ In the light of the above statements, choose the correct answer from the options given below.\

Professor PC Thomas Classes · Answer

(b) :\ This reaction does not require any catalyst.\ Presence of Lewis acid promotes generation of $\mathrm{Br}^{+}$in some reactions, e.g., monohalogenation of benzene and in some other arenes, reaction is carried out at low temperature in the absence of sunlight and in presence of Lewis acid catalyst.\
