`S_(N)1` reaction is faster in

Options

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(|)(C )H - Cl`

Answer

C

Explanation

`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
