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

    A) \[{{C}_{2}}{{H}_{5}}Cl+Mg\xrightarrow{\text{dry}\,\text{ether}}\]

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

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

    D)  \[CHC{{l}_{3}}\xrightarrow{\text{Ag }\,\text{powder}}\]

    Correct Answer: B

    Solution :

    Wurtz reaction: In this reaction alkyl halide reacts with sodium in presence of ether forms alkane. \[C{{H}_{3}}\underset{(Ether)}{\mathop{}}\,\,C{{H}_{3}}\xrightarrow{{}}\underset{\begin{smallmatrix} \text{Ethane} \\ \,\,\,\,\text{(X)} \end{smallmatrix}}{\mathop{{{C}_{2}}{{H}_{6}}}}\,+2NaI\] So, the compound X will be ethane.
