    The  reaction \[{{C}_{2}}{{H}_{5}}ONa+Br{{C}_{2}}{{H}_{5}}\xrightarrow{{}}\]\[{{C}_{2}}{{H}_{5}}-O-{{C}_{2}}{{H}_{5}}+NaBr\]is called

    A)  Frank land reaction

    B) Wurtz reaction

    C)  Williamson's synthesis

    D)  Cannizaro reaction

    Correct Answer: C

    Solution :

    \[{{C}_{2}}{{H}_{5}}ONa+Br-{{C}_{2}}{{H}_{5}}\xrightarrow{{}}{{C}_{2}}{{H}_{5}}-O-{{C}_{2}}{{H}_{5}}+NaBr\] This reaction is called Williamson's synthesis. Note: When sodium alkoxide reacts with alkyl halide to give symmetrical and unsymmetrical ether, such reaction is called Williamson's synthesis.
