Name the product that is obtained when $1, 1-$dimethyloxirane is treated with ${\mathrm{H}}_2{\mathrm{SO}}_4$?

Give products of the given reaction.

A is:

What is the hydrolysis product of the given compound? 

A chiral ${\mathrm{C}}_5{\mathrm{H}}_{10}\mathrm{O}$ ether reacts with hot $\mathrm{HI}$ to give ${\mathrm{C}}_5{\mathrm{H}}_{10}{\mathrm{I}}_2$ as the product. Its treatment with hot $\mathrm{KOH}$ in ethanol produces $1, 3-$pentadiene. What is the structure of the original ether?

Here, $\mathrm{X}$ and $\mathrm{Y}$, respectively, are
