Answer:
; The structures of both compounds are shown in the attached image.
Explanation:
First, compound W has the molecular formula C6H11Cl, it is observed that it does not have double bonds. removal of E2 produces compound Y, which is an alkene, which is hydrogenated and produces a methylcyclopentane.
Compound W is an alkyl halide that undergoes an SN1 reaction with sodium iodide in the presence of acetone forming the corresponding iodine compound.
while compound X is a tertiary alkyl halide, it is sterically restricted to undergo SN2 reactions.
