Racemises of 1- Chloro -1- phenylethane

Question:  A solution of (−)−1 − chloro − 1− phenylethane in toluene racemises slowly in the presence of a small amount of SbCl5, due to the formation of :
(1) carbanion
(2) carbene
(3) carbocation
(4) free radical

Answer:  According to question, (−)−1 − chloro − 1− phenylethane racemises in the presence of SbCl5.


 It  racemises slowly due to formation of intermediate compound.


 This intermediate compound is a carbocation. Thus, option c is correct.
