    C) \[NaB{{H}_{4}}\]

    D) \[Zn/HCl\]

    Correct Answer: B

    Solution :

     \[\underset{n-\text{butane}}{\mathop{C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}C{{H}_{3}}}}\,\underset{\Delta }{\mathop{\xrightarrow{\text{Anhyd}\text{.}\,AlC{{l}_{3}}}}}\,\underset{\text{iso}\,\text{butane}}{\mathop{C{{H}_{3}}-\underset{\underset{\,\,C{{H}_{3}}}{\mathop{|\,\,\,\,\,}}\,}{\mathop{CH}}\,-C{{H}_{3}}}}\,\]
