A) II > I > III > IV
B) III > I > II > IV
C) IV > I > II > III
D) I > II > III > IV
Correct Answer: B
Solution :
In \[-C{{H}_{3}},\,-OC{{H}_{3}}\] and \[C{{F}_{3}},\,C{{H}_{3}}\] and \[-OC{{H}_{3}}\] are electron donating group. Hence, they activate the benzene nucleus. In these, order of activation is \[-OC{{H}_{3}}>-C{{H}_{3}}\] while \[-C{{F}_{3}}\] group deactivates the benzene nucleus. So, it shows lower rate of electrophilic substitution on benzene ring. Thus, order of electrophilic substitution is-You need to login to perform this action.
