Question #45000

Compound $\textbf{X}$ is $\ce{2-O-\alpha-D-glucopyranosyl-L-ascorbic acid}$, a synthetic water-soluble conjugate of Vitamin C. A $1.0\text{ mol}$ sample of $\textbf{X}$ is treated with excess Tollens' reagent (ammoniacal $\ce{AgNO3}$) at $298\text{ K}$, yielding $x\text{ mol}$ of elemental silver precipitate. A separate $1.0\text{ mol}$ sample of $\textbf{X}$ is subjected to complete acidic hydrolysis, carefully neutralized, and then treated with excess Tollens' reagent at $298\text{ K}$, yielding $y\text{ mol}$ of elemental silver precipitate. Assuming standard 2-electron oxidations for all reactive moieties, what are the values of $x$ and $y$?
