Vedclass · Answer

(C) The compound is methyl tert-butyl ether,$(CH_3)_3C-O-CH_3$.To prepare ethers,the Williamson ether synthesis is the most effective method.It involves the reaction of an alkoxide ion with a primary alkyl halide.If a tertiary alkyl halide is used (as in option $A$),elimination (dehydrohalogenation) occurs instead of substitution,leading to an alkene.Therefore,the correct approach is to use a tertiary alkoxide $(CH_3)_3C-OK$ and a primary alkyl halide $(CH_3-Br)$ to undergo $S_N2$ reaction.Reaction: $(CH_3)_3C-OK + CH_3-Br 	o (CH_3)_3C-O-CH_3 + KBr$.

The compound $CH_3-O-C(CH_3)_3$ is prepared best by the reaction:
