In S(N)2 reaction, the correct order of ...

In `S_(N)2` reaction, the correct order of reactivity for following compounds
`CH_(3)Cl,CH_(3)CH_(2)Cl,(CH_(3))_(2)CHCl,(CH_(3))_(3)C-Cl` is

A

`(CH_(3))_(2)CHCl gt CH_(3)CH_(2)Cl gt CH_(3)CL gt (CH_(3))_(3)C Cl`

B

`CH_(3)Cl gt (CH_(3))_(2) CHCl gt CH_(3)CH_(2)Cl gt (CH_(3))_(3)C Cl`

C

`CH_(3)Cl gt CH_(3)CH_(2)Cl gt (CH_(3))_(2)CHCl gt (CH_(3))_(3)C Cl`

D

`CH_(3)CH_(2)Cl gt CH_(3)Cl gt (CH_(3))_(2)CHCl gt (CH_(3))_(3)C Cl`

Text Solution

Verified by Experts

The correct Answer is:
C
As the size of the alkyl group increases in the order: `CH_(3),CH_(3)CH_(2),(CH_(3))_(2)CH,(CH_(3))_(3)C`, steric hindrance increases in the same order and hence the reactivity of the corresponding alkyl halides decreases in the same order, i.e., option (c) is correct.
