Vedclass · Answer

(D) Williamson ether synthesis involves the $S_N2$ reaction of an alkoxide ion with a primary alkyl halide. It cannot be used to prepare ethers where the halide is a vinyl halide,aryl halide,or tertiary alkyl halide because these do not undergo $S_N2$ reactions effectively.$1.$ For $(a)$,the reactants would be $(CH_3)_3C-O^-$ and $CH_2=CH-X$ (vinyl halide) or $CH_2=CH-O^-$ and $(CH_3)_3C-X$ (tertiary halide).$2.$ For $(b)$,the reactants would be $Ph-O^-$ and $Ph-X$ (aryl halide).$3.$ For $(c)$,the reactants would be $CH \equiv C-O^-$ and $CH_2=CH-X$ (vinyl halide).Since none of these reactions are feasible via $S_N2$,none of these ethers can be produced.

Which of the following ethers cannot be produced by Williamson ether synthesis?
