    Butene-1 may be converted to butane by reaction with

    A) \[Zn-HCl\]                          

    B)        \[Sn-HCl\]

    C)        \[Zn-Hg\]                            

    D)        \[Pd/{{H}_{2}}\]

    Correct Answer: D

    Solution :

    \[\underset{butene-1}{\mathop{C{{H}_{2}}=CH}}\,-C{{H}_{2}}C{{H}_{3}}\xrightarrow[\Delta ,\,\,pressure]{Pd/{{H}_{2}}}\]                            \[\underset{\text{butane}}{\mathop{C{{H}_{3}}-C{{H}_{2}}-C{{H}_{2}}-C{{H}_{3}}}}\,\] other reagents are successful with polar double bonds.
