`S_(N)1` reaction is faster in

A

`CH_(3)CH_(2)Cl`

B

C

`CH_(3)-overset(CH_(3))overset(|)underset(CH_(3))underset(|)(C)-Cl`

D

`CH_(3)-underset(CH_(3))underset(|)underset(CH_(2))underset(|)underset(|)(CH)-Cl`

Text Solution

Verified by Experts

The correct Answer is:
C
`S_(N)1` mechanism proceeds through carbocation intermediate.
`CH_(3)-overset(CH_(3))overset(|)underset(CH_(3))underset(|)(C)-Cl` provides stable carbocation intermediate because it has tertiary carbon.
