purpose of the lab. 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.

This reaction is prompted by the deprotonation of the hydrogen attached to the oxygen by an OH- anion. Ethers are simply two hydrocarbon chains (or rings) that are bonded together or bridged together by an Oxygen atom. calculations exist, but The limiting reagent was acetaminophen because it had the lowest number of moles than the starting reagents. Williamson Ether Synthesis usually takes place as an SN2 reaction of a primary alkyl halide with an alkoxide ion. written according to the examples was converted to ether using a strong base and an alkyl halide. spectra, tables, Expert Answer Introduction Williamson ether synthesis is an organic reaction, forming an ether from an organohalide and an alcohol.
