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

  • 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

    Correct Answer: A

    Solution :

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