Williamson ether synthesis report - Hanna Thomson Lab 10 Erica Tuesday 8am Williamson Ether - Studocu Free photo gallery . Purpose of Experiment: 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. IF ON SKIN (or hair): Take off immediately all contaminated clothing. However, as the ring size increases above 4 this proximity effect is trumped by the strong reduction in ring strain. The theoretical yield of the reaction was 1.54 g, The % yield was calculated and found to be 39.81%.
