AIPMT PRELIMS 2007 Chemistry Electrophilic Substitution MCQ Question
Type: MCQ-conceptual-Medium-Class 11
The order of decreasing reactivity towards an electrophilic reagent, for the following would be (i) benzene (ii) toluene (iii) chlorobenzene (iv) phenol
A
(a) (ii) > (iv) > (i) > (iii)
B
(b) (iv) > (ii) > (i) > (iii)
C
(c) (iv) > (iii) > (i) > (ii)
D
(d) (i) > (ii) > (iii) > (iv)
Correct Answer
Option B
Detailed Explanation
Phenol is most reactive due to the electron-donating effect of the -OH group, followed by toluene due to the -CH₃ group. Benzene is less reactive than both, and chlorobenzene is least reactive due to the electron-withdrawing effect of chlorine.
