    Which of the following is expected to be optically active?

    A)  \[{{(C{{H}_{3}})}_{4}}C\]

    B)         \[{{({{C}_{2}}{{H}_{5}})}_{2}}CH\cdot C{{H}_{3}}\]

    C)         \[{{C}_{2}}{{H}_{5}}CH(C{{H}_{3}})\cdot {{C}_{3}}{{H}_{7}}\]

    D)         \[C{{H}_{3}}CH\overline{\,\,\,\,\,\,\,}\overline{\,\,\,\,\,\,\,}CH\cdot C{{H}_{3}}\]

    Correct Answer: C

    Solution :

    \[{{C}_{2}}{{H}_{5}}\underset{{{C}_{3}}{{H}_{7}}}{\overset{H}{\mathop{-\underset{|}{\overset{|}{\mathop{{{C}^{*}}}}}\,}}}\,-\,\,\,\,C{{H}_{3}}\] 3-methyl hexane has a chiral carbon atom, hence, is optically active. Though it shows very little rotation in plane of plane polarized light.
