Ethyl iodide in the presence of a base. In this experiment, 1.54 g of Phenacetin is collected. The theoretical yield of the reaction was 1.54 g, The % yield was calculated and found to be 39.81%. Wash skin thoroughly after handling. Alkoxides consist of the conjugate base of an alcohol and are comprised of an R group bonded to an oxygen atom. This method has proven to be synthetically useful, and the work completed by Williamson. Chemical Ethers are simply two hydrocarbon chains (or rings) that are bonded together or bridged together by an Oxygen atom.
