  • An important route to unsymmetrical ethers is a nucleophilic substitution reaction known as the Williamson synthesis. This synthesis consists of an S_(N)2 reaction of a sodium alkoxide with an alkyl halide, alkyl sulphonate or alkyl sulphate. By a proper choice of reagents, both symmetrical and unsymmetrical ethers can be prepared by Williamson synthesis. The reverse process of cleavage of ethers to give back the original alkyl halide and the alcohol can be carried out by heating the ether with HI at 373 K. Benzyl ethyl ether reacts with HI to form

    A
    p-iodotoulene and ethyl alcohol
    B
    benzyl alcohol and ethyl iodide
    C
    phenol and ethyl iodide
    D
    iodobenzene and ethyl alcohol
