Which of the following is incorrect order of decreasing reactivity towards electrophilic aromatic substitution?
  1. Fluoro benzene > chloro benzene > bromo benzene
  2. Phenol > n-propyl benzene > benzoic acid
  3. Chloro toluene > para-nitro toluene > 2-chloro-4-nitro toluene
  4. Benzoic acid > phenol > n-propyl benzene

Solution

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