    Butene-1 may be converted to butane by reaction with     AIEEE  Solved  Paper-2003

    A) \[Zn-HCl\]                          

    B) \[Sn-HCl\]

    C) \[Zn-Hg\]

    D) \[Pd/{{H}_{2}}\]

    Correct Answer: D

    Solution :

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