Vedclass · Answer

(C) Williamson's synthesis involves the reaction of an alkyl halide with a sodium alkoxide to form an ether. For the reaction to proceed via an $S_N2$ mechanism,the alkyl halide should be primary $(1^\circ)$ to minimize steric hindrance. If a tertiary alkyl halide is used,elimination (forming an alkene) predominates over substitution. Therefore,to prepare $tert$-butyl methyl ether,we should use a primary alkyl halide $(CH_3Br)$ and a tertiary alkoxide $((CH_3)_3CONa)$. This corresponds to option $C$.

The substances used for the preparation of ether by Williamson's synthesis are:
