The difference in the reaction of phenol with bromine in chloroform and bromine in water medium is due to

Options

AHyperconjugation in substrate
BPolarity of solvent
CFree radical formation
DElectromeric effect of the substrate

Correct answer

B. Polarity of solvent

Step-by-step solution

Difference in reactions is observed due to solvent polarity, which (i) Ionizes phenol to make more reactive phenoxide ion (ii) Increases electrophilicity of bromine.
