• # 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) $C{{H}_{3}}-CHOH-C{{H}_{2}}C{{H}_{3}}$

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