    Wurtz reaction of methyl iodide yields an organic compound X. Which of the following reaction also yields X?

    A)  \[{{C}_{2}}{{H}_{5}}Cl+LiAl{{H}_{4}}\xrightarrow{{}}\]

    B)  \[{{C}_{2}}{{H}_{5}}Cl+Mg\xrightarrow{Dry\text{ }ether}\]

    C)  \[{{C}_{2}}{{H}_{5}}Cl+{{C}_{2}}{{H}_{5}}ONa\xrightarrow{{}}\]

    D)  \[CHC{{l}_{5}}Cl+Ag(powder)\xrightarrow{\Delta }\]

    Correct Answer: A

    Solution :

                    \[2C{{H}_{3}}+2Na\xrightarrow{Dry\text{ }ether}\underset{ethane}{\mathop{C{{H}_{3}}-C{{H}_{3}}}}\,+2Nal\] \[4{{C}_{2}}{{H}_{5}}Cl+LiAl{{H}_{4}}\xrightarrow{{}}\underset{ethane}{\mathop{4{{C}_{2}}{{H}_{6}}}}\,+AlC{{l}_{3}}+LiCl\]
