Chemistry20262 marksIdentify
An organic compound [X] with molecular formula $\text{C}_2\text{H}_4\text{O}$ forms compound [Y] on oxidation. Compound [X] undergoes haloform reaction. On treatment with $\text{HCN}$, compound [X] forms a product [Z] which on hydrolysis gives 2-hydroxy propanoic acid. (a) Write down the structures of compounds [X] and [Y]. (b) Name the product formed when [X] reacts with dil. $\text{NaOH}$.
