Text Solution
Verified by ExpertsThe correct answer is:
C
The rate of nucleophilic substitution reaction decreases in the presence of electron releasing
group at orthu and para position w.r.t. to chlorine. Compound (iii) has two electron releasing groups and compound (ii) has one electron releasing group w.r.t chlorine while compound (i) has no electron releasing group.
So, the rate of nucleophilic substitution reaction is highest in compound (i) and order is (iii) < (ii) < (i).
