    A) \[~C{{H}_{3}}I\]                 

    B) \[{{C}_{2}}{{H}_{5}}OH\]

    C) \[~C{{H}_{3}}OH\]                        

    D) \[~C{{H}_{3}}C{{H}_{2}}I\]

    Correct Answer: A

    Solution :

    \[C{{H}_{3}}I+2H\xrightarrow[or\,Zn-Cu/{{C}_{2}}{{H}_{5}}OH]{Zn+HCl}\underset{Methane}{\mathop{C{{H}_{4}}}}\,+HI\] \[C{{H}_{3}}I+2Na+IC{{H}_{3}}\xrightarrow{Dry\,water}\underset{Ethane}{\mathop{C{{H}_{3}}}}\,.C{{H}_{3}}+2NaI\]Hence, the correct option is [a].
