We finally weighed the container again to determine The purpose of the experiment was to perform the Williamson ether synthesis, a specific type of, reaction where an alcohol is converted into a nucleophile through the utilization of a base, and, reacts with an alkyl halide through an SN2 mechanism. Alkoxides consist of the conjugate base of an alcohol and are comprised of an R group bonded to an oxygen atom. Phenacetin is prepared by mixing 1.300 g of, Ethyl iodide in the presence of a base.
