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.
