    A solution of (+)-2-chloro-2-phenylethane in toluene racemises slowly in the presence of small amount of \[SbC{{l}_{2}}\] due to the formation of

    A)  carbanion                  

    B)  carbene

    C)  free radical                 

    D)  carbocation

    Correct Answer: D

    Solution :

    \[{{C}_{6}}{{H}_{5}}-\underset{H}{\mathop{\underset{|}{\mathop{\overset{Cl}{\mathop{\overset{|}{\mathop{C}}\,}}\,}}\,}}\,-C{{H}_{3}}+SbC{{l}_{3}}\underset{Carbocation}{\mathop{{{C}_{6}}{{H}_{5}}-\overset{+}{\mathop{\underset{H}{\mathop{\underset{|}{\mathop{C}}\,}}\,}}\,-C{{H}_{3}}+SbCl_{6}^{-}}}\,\] The planar carbonation, when return back form racemic mixture of the starting compounds.
