Q. Which of the following compounds are not arranged on order of decreasing reactivity towards electrophilic substitution?
A) Fluorobenzene > chlorobenzene > bromo benzene
B) Phenol> $n$-propyl benzene> benzoic acid>
C) Chlorotoluene >$para$-nitrotoluene>2-chloro-4-nitro toluene
D) Benzoic acid> phenol>$n$-propyl benzene
Explanation
(d)
$\because\ - COOH$ group is a deactivating group
$\therefore$ Benzoic acid is less reactive towards electrophilic substitution.
So, benzoic acid> phenol>n-propyl benzene is not arranged correctly.
