Text Solution
Verified by ExpertsThe correct answer is:
D
The rate of nucleophilic substitution reaction decreases in presence of electron releasing
group at ortho or para position. In compound (iii), electron releasing group is present at meta position w.r.t. chlorine, so the impact is less but in compound (ii) it will be present at ortho position.
Thus, the rate of reaction towards nucleophilic substitution is least in compound (ii) and highest in compound (i) as there is no electron releasing group in this compound.
