    D) 2-methylpentane

    Correct Answer: B

    Solution :

               \[\begin{matrix}    \,\,\,\,\,\,\,\,\,\,C{{H}_{3}}\,C{{H}_{3}}  \\    |\,\,\,\,\,\,\,\,\,\,\,|  \\    {{H}_{3}}C-CC-C{{H}_{3}}  \\    |\,\,\,\,\,\,\,\,\,\,\,\,|  \\    H\,\,\,\,\,\,\,\,H  \\ \end{matrix}\xrightarrow{C{{l}_{2}}}\,\]\[\begin{matrix}    \,\,\,\,\,C{{H}_{2}}Cl\,\,\,C{{H}_{3}}  \\    |\,\,\,\,\,\,\,\,\,\,\,\,\,|  \\    {{H}_{3}}C-CC-C{{H}_{3}}  \\    |\,\,\,\,\,\,\,\,\,\,\,\,|  \\    H\,\,\,\,\,\,\,\,H  \\ \end{matrix}+\begin{matrix}    \,\,\,\,\,\,\,C{{H}_{3}}\,\,\,C{{H}_{3}}  \\    |\,\,\,\,\,\,\,\,\,\,\,\,\,\,|  \\    {{H}_{3}}C-CC-C{{H}_{3}}  \\    |\,\,\,\,\,\,\,\,\,\,\,\,|  \\    Cl\,\,\,\,\,\,H  \\ \end{matrix}\]
