What are the major products X and Y respectively in the following reactions? $\begin{aligned} & \left(\mathrm{CH}_3\right)_3 \mathrm{CONa}+\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{Br} \rightarrow \mathrm{X} \\ & \left(\mathrm{CH}_3\right)_3 \mathrm{CBr}+\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{ONa} \rightarrow \mathrm{Y} \end{aligned}$
  1. $\mathrm{CH}_2=\mathrm{CH}_2,\left(\mathrm{CH}_3\right)_3 \mathrm{COCH}_2 \mathrm{CH}_3$
  2. $\left(\mathrm{CH}_3\right)_3 \mathrm{COCH}_2 \mathrm{CH}_3,\left(\mathrm{CH}_3\right)_3 \mathrm{COCH}_2 \mathrm{CH}_3$
  3. $\mathrm{CH}_2=\mathrm{CH}_2,\left(\mathrm{CH}_3\right)_2 \mathrm{C}=\mathrm{CH}_2$
  4. $\left(\mathrm{CH}_3\right)_3 \mathrm{COCH}_2 \mathrm{CH}_3,\left(\mathrm{CH}_3\right)_2 \mathrm{C}=\mathrm{CH}_2$

Solution


The reaction involves $\mathrm{S}_{\mathrm{N}} 2$ attack of an alkoxide ion on alkyl halide.
