A) Methoxy benzene > Toluene > Bromo benzene
B) Phenol > N-Propyl benzene > Benzoic acid
C) Chlorotoluene > Para Nitro toluene > 2-chloro-4-Nitrotoluene
D) Benzoic acid > Phenol > N-Propyl benzene
Correct Answer: D
Solution :
Amongst the sets, it is [d] that is not arranged in the order of decreasing reactivity towards electrophilic substitution. Carboxylic acid group in the case of benzoic acid deactivates the benzene nucleus towards electrophilic substitution reaction and thus it cannot have higher reactivity than phenol which has a highly activating phenolic OH group.You need to login to perform this action.
