    C)  2, 3-dimethylpentane

    D)  2, 3, 4-trimethylpentane

    Correct Answer: C

    Solution :

    : \[\underset{2,3-dimethylpentane}{\mathop{{{H}_{3}}C-\underset{\begin{smallmatrix}  | \\  {{H}_{3}}C \end{smallmatrix}}{\overset{\begin{smallmatrix}  H \\  | \end{smallmatrix}}{\mathop{C}}}\,-\underset{\begin{smallmatrix}  | \\  C{{H}_{3}} \end{smallmatrix}}{\overset{\begin{smallmatrix}  H \\  | \end{smallmatrix}}{\mathop{{{C}^{*}}}}}\,\overset{chiral\text{ }centre}{\mathop{-{{H}_{2}}C-C{{H}_{3}}}}\,}}\,\]
