Option (iv) is the answer.
The presence of an electron-releasing group in the ortho or para locations slows down nucleophilic substitution.
arrange the compounds in increasing order of the rate of reaction towards nucleophilic substitution.(i) (a) < (b) < (c) (ii) (a) < (c) < (b) (iii) (c) < (b) < (a) (iv) (b) < (c) < (a)
