Question

Which of the following is incorrect order of decreasing reactivity towards electrophilic aromatic substitution? (A) Fluoro benzene > chloro benzene > bromo benzene (B) Phenol > n-propyl benzene > benzoic acid (C) Chloro toluene > para-nitro toluene > 2-chloro-4-nitro toluene (D) Benzoic acid > phenol > n-propyl benzene

-COOH group is a deactivating group, hence benzoic acid is less reactive towards electrophilic substitution than phenol.

Fluoro benzene > chloro benzene > bromo benzene

Phenol > n-propyl benzene > benzoic acid

Chloro toluene > para-nitro toluene > 2-chloro-4-nitro toluene

Benzoic acid > phenol > n-propyl benzene

$- COO H$ group is a deactivating group, hence benzoic acid is less reactive towards electrophilic substitution than phenol.
