    The conversion of ethyl chloride into diethyl ether takes place by

    A)  Williamsons synthesis

    B)  Perkins reaction

    C)  Wurtz reaction

    D)  Grignard reaction

    Correct Answer: A

    Solution :

    Williamsons synthesis \[{{C}_{2}}{{H}_{5}}ONa+Cl{{C}_{2}}{{H}_{5}}\xrightarrow{{}}\underset{\text{Diethyl}\,\text{ether}}{\mathop{{{C}_{2}}{{H}_{5}}O{{C}_{2}}{{H}_{5}}}}\,+NaCl\] Wurtz reaction: \[{{C}_{2}}{{H}_{5}}{{C}_{2}}\xrightarrow{ether}\underset{\text{Butane}}{\mathop{{{C}_{2}}{{H}_{5}}-{{C}_{2}}{{H}_{5}}}}\,\]\[+\,2NaCl\]
