Vedclass · Answer

(D) The Williamson ether synthesis involves the reaction of an alkyl halide with an alkoxide. For the reaction to produce an ether,the alkyl halide should ideally be primary $(1^o)$ to favor $S_N2$ substitution. In option $D$,the reactant is a tertiary $(3^o)$ alkyl halide $(CH_3-C(CH_3)_2-Cl)$. Tertiary alkyl halides undergo elimination reactions in the presence of strong bases (like alkoxides) to form alkenes as the major product,rather than ethers. Therefore,in reaction $D$,an ether is not the main product.
