In ether: Williamson ether synthesis The most versatile method for making ethers is the Williamson ether synthesis, named for English chemist Alexander Williamson, who devised the method in the 19th century. Risk Statements- Purpose The original procedure, was flawed because the components led to low reaction rates (cresol and NaOH formed a low, solubility sodium cresolate), but by adding tetra(n-butyl) ammonium bromide as a catalyst the, experiment is much more successful. Details, 4 pts: Minor errors exist Williamson ether synthesis is two steps Quick Procedure You're going to add ~5 mL of methanol, two boiling stones, and your starting materials (2-hydroxynaphthalene, sodium hydroxide, and ethyl iodide) into a 50-mL round bottom flask and reflux it for about 30 minutes. Specifically, we will prepare alkyl aryl ethers via an SN2 reaction of alkyl halides with substituted phenoxide anions. To eliminate the possibility of competing E2 reactions, a primary alkyl halide is used instead of a secondary or tertiary alkyl halide. There are several examples given below for the synthesis of ethers: 4.2. 8. IF ON SKIN (or hair): Take off immediately all contaminated clothing. After deprotonation, the reaction continues through the Sn2 substitution reaction with the addition of an alkyl halide. Which indicates that the experiment was a success. Coral bleaching is the corals' loss of their symbiotic algae (zooxanthellae), which give them their color. the separatory funnel along with 5 mL of dichloromethane, mixed with proper venting, and then Rinse skin with water/ shower. is correct.

Problems Set 4 with Solutions on Ethers | CHEM 30B. Ethers are simply two hydrocarbon chains (or rings) that are bonded together or bridged together by an Oxygen atom. Dispose of chemicals in their respective containers. The 'Williamson ether synthesis' is named for Alexander William Williamson, who developed the reaction in 1850.
