Using a Williamson synthesis, and make the appropriate choices when deciding how best synthesize. The key bond cleavage in the target molecule involves a C-O bond. So let's look at the mechanism if i use methyl fluoride or chloride is there any problem.

(See post: The SN2 Mechanism), [Side note: when Williamson reported the reaction in 1850 he didnt know what an SN2 was scientists didnt even know what electrons were, for that matter which again goes to show that the science of organic chemistry developed through a lot of empirical observations first, and the theory developedlater.]. Draw the electron arrow pushing mechanism for the formation of diethyl ether in the previous problem. K2CO3 could deprotonate the alcohol resulting in the alkoxide, which is more nucleophilic than the free alcohol and will perform the SN2 reaction much faster. We know that alcohols can Most 1o, 2o, 3o alcohols can be successfully used for this reaction. 18: Ethers and Epoxides; Thiols and Sulfides, { "18.00:_Introduction" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.
The Ethers produced in this way have more carbon atoms than either of the starting materials and thus are more complex structures. (i) Name the product Answer any FOUR of the following questions. Do you notice something wrong here?
