The increasing order of the rate of reaction towards nucleophilic substitution in the following compounds is:
I < II < III
II I< II < I
I < III < II
III < I < III
Presence of an electron withdrawing group such as -NO2 group at the ortho and para positions will withdraw electron density by -R and -I while at meta position only -I will be implemented.
In the question arrange the compounds in increasing order of rate of reaction towards nucleophilic substitution.
(a) (i) < (ii) < (iii) (b) (ii) < (i) < (iii) (c) (iii) < (ii) < (i) (d) (i) < (iii) < (ii)
