    A)  \[C{{H}_{3}}COOH\]                      

    B)  \[C{{H}_{3}}.CHO\]

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

    D)  \[C{{H}_{3}}.C{{H}_{3}}\]

    Correct Answer: D

    Solution :

                     \[\underset{\text{methyl}\,\text{alcohol}}{\mathop{C{{H}_{3}}OH}}\,+CO\xrightarrow{\text{Rh}\,\text{catalyst}}\underset{\begin{smallmatrix}  \,\,\,\,\,\,\,\,\,(A) \\  acetic\,acid \end{smallmatrix}}{\mathop{C{{H}_{3}}COOH}}\,\] \[\xrightarrow[red\,P]{HI+}\underset{\begin{smallmatrix}  \,\,\,(B) \\  ethane \end{smallmatrix}}{\mathop{C{{H}_{3}}-C{{H}_{3}}}}\,\]
