Q. Arrange decreasing order of reactivity of these compounds for nucleophilic substitution reaction.

$\left(\right.1\left.\right)$ Question

$\left(\right.2\left.\right)$ $CH_{3}-CH_{2}-O-TsCl$

$\left(\right.3\left.\right)$ $CH_{3}-CH_{2}-Cl$

$\left(\right.4\left.\right)$ $CH_{3}-CH_{2}-Br$

Solution:

For nucleophilic substitution reaction the decreasing order of reactivity is given as

Solution

Leaving power in decreasing order is as follows

$-O-SO_{2}-CF_{3}>-OTs>Br>Cl$
