    D)  \[Zn/HCl\]

    Correct Answer: B

    Solution :

    \[C{{H}_{3}}-\underset{n-\text{butane}}{\mathop{C{{H}_{2}}-C{{H}_{2}}}}\,-C{{H}_{3}}\xrightarrow{AlC{{l}_{3}}/HCl}\] \[\underset{\text{isobutane}}{\mathop{C{{H}_{3}}-\overset{C{{H}_{3}}}{\mathop{\overset{|}{\mathop{C}}\,}}\,H-C{{H}_{3}}}}\,\]
