`SN^(1)` reaction of alkyl halides leads to

Options

A. retention of configuration
B. racemisation
C. inversion of configuration
D. None of the above

Answer

B

Explanation

In `SN^(1)` mechanism, carbonium ion is formed as intermediate. Hence, hybridisation of carbon changes from `sp^(3)` to `sp^(2)`. One p-orbital remain vacant, so reagent can attach with both lobes of p-orbital and forms racemic mixture.
