(+)-2-chloro-2-phenylethane in toluene racemises slowly in the presence of small amount of \(\mathrm{SbCl}_{5},\) due to the formation of
- A carbanion
- B carbene
- C free-radical
- D carbocation
Answer & Solution
Correct Answer
(D) carbocation
Step-by-step Solution
Detailed explanation
A planar carbocation is generated when \(\mathrm{SbCl}_{5}\) remove \(\mathrm{Cl}^{-}\) from the substrate. This carbocation is subsequently attacked by \(\mathrm{Cl}^{-}\) (nucleophile) from both the sides (j.e. from top and bottom) to produce a racemic mixture.
