Arrange the following halides in order of increasing `S_N^(2)` reactivity:
`CH_3Cl, CH_3Br , CH_3 CH_2 Cl, (CH_3)_2CHCl`.

Text Solution

Verified by Experts

The correct Answer is:
`(CH_3)_2CHCl lt CH_3 CH_2 Cl lt CH_3Cl lt CH_3Br`
`S_(N^2)` reactivity decreases with increase in size of alkyl group. `CH_3Br` is more reactive than `CH_3Cl` because `C - Cl`. Bond is stronger than C - Br bond.
