• question_answer Which of the following compounds is not chiral [CBSE PMT 1998; DPMT 2002] A) $DC{{H}_{2}}C{{H}_{2}}C{{H}_{2}}Cl$ B) $C{{H}_{3}}C{{H}_{2}}CHDCl$ C) $C{{H}_{3}}CHDC{{H}_{2}}C{{H}_{2}}Cl$ D) $C{{H}_{2}}CHClC{{H}_{2}}D$

$DC{{H}_{2}}-C{{H}_{2}}-C{{H}_{2}}-Cl$ Others are chiral $C{{H}_{3}}-C{{H}_{2}}-\overset{H\,\,\,\,}{\mathop{\overset{|\,\,\,\,\,}{\mathop{\underset{Cl}{\mathop{\underset{|\,\,\,\,\,}{\mathop{{{C}^{*}}}}\,}}\,}}\,}}\,-D$; $C{{H}_{3}}-\underset{D\,\,}{\overset{H\,\,}{\mathop{\underset{|\,\,\,\,}{\overset{|\,\,\,\,}{\mathop{{{C}^{*}}}}}\,}}}\,-C{{H}_{2}}-C{{H}_{2}}-Cl$    $C{{H}_{3}}-\underset{Cl\,\,}{\overset{H\,\,}{\mathop{\underset{|\,\,\,\,}{\overset{|\,\,\,\,}{\mathop{{{C}^{*}}}}}\,}}}\,-C{{H}_{2}}D$
