A) (i) > (ii) > (iii) > (iv)
B) (ii) > (iv) > (i) > (iii)
C) (iv) > (iii) > (ii) > (i)
D) (iv) > (ii) > (i) > (iii)
Correct Answer: D
Solution :
Benzene having any activating group i.e., OH, R etc., undergoes electrophilic substitution very easily as compared to benzene itself. Thus toluene \[({{C}_{6}}{{H}_{5}}C{{H}_{3}}),\] phenol \[({{C}_{6}}{{H}_{5}}OH)\] undergo electrophilic substitution very readily than benzene. Chlorine with +E and +M effect deactivates the ring due to strong ?I effect. So, it is difficult to carry out the substitution in chlorobenzene than in benzene, so correct order is \[\underset{(iv)}{\mathop{Phenol}}\,>\underset{(ii)}{\mathop{Toluene}}\,>\underset{(i)}{\mathop{Benzene}}\,\] \[>\underset{(iii)}{\mathop{Chlorobenzene}}\,\]You need to login to perform this action.
