JEE Main & Advanced Chemistry GOC Question Bank Structural and stereo isomerism

  • question_answer Which of the following compounds is optically active [Pb. PMT 2001; AMU 2002; Kerala (Med.) 2003]

    A) \[{{(C{{H}_{3}})}_{2}}CHC{{H}_{2}}OH\]

    B) \[C{{H}_{3}}C{{H}_{2}}OH\]

    C) \[CC{{l}_{2}}{{F}_{2}}\]

    D) \[C{{H}_{3}}CHOH{{C}_{2}}{{H}_{5}}\]

    Correct Answer: D

    Solution :

    \[\underset{\,\,\,\,\,\,\,\,\,\,\,\,\,{{C}_{2}}{{H}_{5}}}{\mathop{\underset{\,\,\,\,\,|}{\mathop{\overset{\,\,\,\,\,\,\,\,\,\,\,\,OH}{\mathop{\overset{\,\,\,\,\,\,\,\,|*}{\mathop{C{{H}_{3}}-C-H}}\,}}\,}}\,}}\,\] In this structure chiral carbon is present that is why it is optically active.
