Q. Which of the following is incorrect order of decreasing reactivity towards electrophilic aromatic substitution?
NTA Abhyas
NTA Abhyas 2020
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
Solution:
$-COOH$ group is a deactivating group, hence benzoic acid is less reactive towards electrophilic substitution than phenol.
