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.
