The decreasing order of $S_{N} 2$ reaction for the given compounds is

Options:

Answer:

Solution:

Rate of $S_{N} 2$ reaction $\propto - I$ -effect, $- M$ -effect $\propto \frac{1}{steric crowding}$ I. $CH_{3} - CH_{2} - CH_{2} - Cl$ II. $Ph - CH_{2} - CH_{2} - Cl$
Thus, rate of $S_{N} 2$ reaction is II $> I >$ III $>$ IV
