A compound that undergoes bromination easily is
Options
(a) toluene
(b) benzoic acid
(c) phenol
(d) benzene
Correct Answer:
phenol
Explanation:
phCH₃ , phCOOH, phOH, phH, Among the given compounds , phCH₃ and phOH have activating groups, -OH and -CH₃, -OH has a strong +R effect and CH₃ has +I effect and hyperconjugative effect, +R effect being stronger than the +I and hyperconjugative effect, phOH will undergo the reaction more readily than phCH₃. Again phCOOH is deactivaing group. phH has neither a deactivating nor an activating group, so it will be more reactive than the compounds with deactivating groups. Phenol undergoes bromination easily even in absence of any halogen carrier.

Due to oh group ring becomes more active in substitution rxn.
