desire to prepare ethyl isopropyl ether using ethyl alcohol and isopropyl alcohol. You have available as inorganic reagents sodium metal and hydrochloric acid. Although either alcohol could produce an alkoxide ion and either alcohol could undergo substitution to give an alkyl halide, the Williamson synthesis of the desired ether woudl favor one particular alkoxide ion-alkyl halide combination. Write the chemical equation for the formation of the favored alkyl halide, alkoxide ion, and ether.
