Vedclass · Answer

(B) Analysis of reactions:$P$: Reaction of $t$-butoxide $(t-BuO^-)$ with $t$-butyl bromide $(t-BuBr)$. Since $t-BuO^-$ is a strong base and $t-BuBr$ is a tertiary halide,elimination $(E2)$ is favored,yielding isobutylene $(4)$ and $t$-butanol $(1)$.$Q$: Reaction of $t$-butyl methyl ether with $HBr$. This is an acid-catalyzed cleavage of ether,yielding $t$-butyl bromide $(2)$ and methanol.$R$: Reaction of $t$-butyl bromide with $NaOMe$. Since $NaOMe$ is a strong base and $t-BuBr$ is a tertiary halide,elimination $(E2)$ is favored,yielding isobutylene $(4)$.$S$: Reaction of $t$-butoxide with methyl bromide $(MeBr)$. This is an $S_N2$ reaction,yielding $t$-butyl methyl ether $(3)$.Matching: $P$ $\rightarrow 1, 4; Q$ $\rightarrow 2; R$ $\rightarrow 4; S$ $\rightarrow 3$.
