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

  • question_answer Which of the following has chiral structure

    A) \[C{{H}_{3}}-\overset{C{{H}_{3}}\,\,}{\mathop{\overset{|\,\,\,\,\,\,\,\,\,}{\mathop{CH-\,}}\,}}\,C{{H}_{2}}COOH\]

    B) \[C{{H}_{3}}-CH=CH-C{{H}_{3}}\]

    C) \[C{{H}_{3}}-\overset{C{{H}_{3}}}{\mathop{\overset{|\,\,\,\,\,\,\,\,}{\mathop{CH-\,}}\,}}\,C{{H}_{2}}OH\]

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

    Correct Answer: D

    Solution :

      \[C{{H}_{3}}-\underset{OH}{\overset{H\,\,}{\mathop{\underset{|\,\,\,\,}{\overset{|\,\,\,\,}{\mathop{{{C}^{*}}\,}}}\,}}}\,-C{{H}_{2}}-C{{H}_{3}}\] Chiral structure is that in which one carbon atom is attached to 4 different atoms or groups.
