  • question_answer
    A solution of(+) - 2 - chloro - 2 - phenylethane in toluene racemises slowly in the presence of small amounts of \[SbC{{l}_{5}}\] due to the formation of

    A) Carbanion         

    B) Carbene

    C) Free radical      

    D) Carbocation

    Correct Answer: D

    Solution :

    [d] \[SbC{{l}_{5}}\] pulls \[C{{l}^{-}}\]to form \[SbCl_{6}^{-}\] leaving behind planar \[{{C}_{6}}{{H}_{5}}-\overset{+}{\mathop{C}}\,H-C{{H}_{3}}\] carbonium ion. It can be attacked from either side leading to racemic mixture.
