    The product obtained on reaction of \[{{C}_{2}}{{H}_{5}}Cl\]with hydrogen over palladium is

    A) \[{{C}_{2}}{{H}_{4}}\]                 

    B) \[{{C}_{3}}{{H}_{8}}\]     

    C)      \[{{C}_{2}}{{H}_{6}}\]     

    D)      \[{{C}_{4}}{{H}_{10}}\]                           

    Correct Answer: C

    Solution :

    \[RX\xrightarrow[Zn/HCl\,or]{{{H}_{2}}/Pd\,or}\underset{Alkane}{\mathop{RH}}\,+HX\] \[(X=Br,I)Zn/Cu/{{C}_{2}}{{H}_{5}}OH\] \[{{C}_{2}}{{H}_{5}}Cl\xrightarrow[\text{Reagents}]{\text{Any of the above}}{{C}_{6}}{{H}_{6}}+HCl\] Hence, the correct option is (c).
