An aliphatic compound $[\mathrm{X}]$, Molecular formula $\left(\mathrm{C}_4 \mathrm{H}_{10} \mathrm{O}\right)$ can be prepared from Acetone and $\mathrm{R}-\mathrm{Mg}-\mathrm{X}$.
$[\mathrm{X}]$ with $20 \%$ Phosphoric acid gives an unsaturated compound $\mathrm{C}_4 \mathrm{H}_8[\mathrm{Y}]$. Compound $[\mathrm{Y}]$ is also obtained on heating $[\mathrm{X}]$ with Copper metal at 573 K . $[\mathrm{X}]$ shows no reaction with PCC but on heating with acidified $\mathrm{KMnO}_4$ it forms Acetone $+\mathrm{CO}_2+\mathrm{H}_2 \mathrm{O}$.
Compounds $[\mathrm{X}]$ and $[\mathrm{Y}]$ are $\_\_\_\_$ and $\_\_\_\_$
