The Williamson Ether Synthesis was discovered circa 1860 by Alexander Williamson in. Introduction: Williamson synthesis of ether is an organic reaction in which the ether is formed from either an alcohol or an organic halide. Percentage yield is the calculation of the final product. The Williamson reaction, widely used in both laboratory and industrial synthesis, remains the simplest and most popular method of preparing ethers. including product name and reac- Explanations for - Flammability: What additional evidence could you use to determine your product is phenacetin? chemical theory. a) the percent yield if only 3.615 of product is obtained. The Williamson Ether synthesis is one of several organic chemistry reactions referred to as Named Reactions, which employ the name of the scientist who developed it. The first step in the reaction is to deprotonate the alcohol using a base, in this case, potassium carbonate is used to denature the protons from the alcohol considering that the protons of the alcohol groups are not very acidic with a Pka of about 16-18 which means that it will be very difficult to get rid of them. Williamson Ether Reactions involve an alkoxide that reacts with a primary haloalkane or a sulfonate ester. . Rinse skin with water/ shower.
