• # question_answer Which will have enantiomer [BVP 2004] A) $C{{H}_{3}}C{{H}_{2}}\underset{Cl\ }{\mathop{\underset{|}{\mathop{C}}\,H}}\,-C{{H}_{3}}$ B) $C{{H}_{2}}C{{H}_{2}}C{{H}_{2}}C{{H}_{2}}Cl$ C) $C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}CHC{{l}_{2}}$ D) None

2-chloro butane has a chiral carbon atom, hence only it will show optical activity and will possess two enantiomers (one chiral carbon atom). $C{{H}_{3}}C{{H}_{2}}-\underset{Cl\ }{\mathop{\overset{H}{\mathop{\underset{|}{\overset{|}{\mathop{{{C}^{\bullet }}}}}\,}}\,-}}\,C{{H}_{3}}$
