Arrange the following compounds in order of increasing reactivity to electrophilic aromatic substitution. bromobenzene nitrobenzene benzene phenol

Question

Quizplus · Accepted Answer

Nitrobenzene is the least reactive due to the strong electron-withdrawing effect of the nitro group. Bromobenzene is less reactive than benzene due to the electron-withdrawing nature of bromine, but more reactive than nitrobenzene. Benzene is more reactive than both nitrobenzene and bromobenzene. Phenol is the most reactive due to the electron-donating effect of the hydroxyl group.
