• # question_answer Which of the following will be chiral [J & K 2005] A) $C{{H}_{3}}CHC{{l}_{2}}$ B) $C{{H}_{3}}CHBrCl$ C) $C{{D}_{2}}C{{l}_{_{2}}}$ D) $C{{H}_{2}}ClBr$

$\underset{H}{\mathop{\underset{|}{\mathop{\overset{\,\,\,\,\,\,\,C{{H}_{3}}}{\mathop{\overset{|}{\mathop{Br-{{C}^{*}}-Cl}}\,}}\,}}\,}}\,$    * asymmetric or chiral carbon All the four valencies of carbon are satisfied with different atoms/substituents.
