A solution of $$(-) -2$$-chloro-$$2$$-phenylethane in toluene racemises slowly in the presence of a small amount of $$SbCl_{5}$$, due to the formation of:

ACarbene
BCarbocation
Correct Answer
CFree radical
DCarbanion

Solution

A solution of $$(-) -1$$-chloro-$$1$$-phenylethane in toluene racemises slowly in the presence of a small amount of $$SbCl_{5}$$, due to the formation of carbocation. Carbocation has planar geomety. Hence, the nucleophile can attack from either side.
