In the reaction sequence: $CH_2OH-CHOH-CH_2OH$ $\xrightarrow{KHSO_4/\Delta} (X)$ $\xrightarrow{(C_2H_5O)_3Al/\Delta} (Y)$,$(Y)$ will be:

An organic compound contains $69.77 \%$ carbon,$11.63 \%$ hydrogen and the rest is oxygen. The molecular mass of the compound is $86$. It does not reduce Tollens' reagent but forms an addition compound with sodium hydrogensulphite and gives a positive iodoform test. On vigorous oxidation,it gives ethanoic acid and propanoic acid. Write the possible structure of the compound.
