Question: Which of the following compounds are not arranged in order of decreasing reactivity towards electrophilic substitution [DCE 2003]
Options:
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
