Vedclass · Answer

(D) Periodic acid $(HIO_4)$ cleaves vicinal diols ($1$,$2$-diols) and $\alpha$-hydroxy carbonyl compounds. For structure $X$: The cyclic structure has three adjacent hydroxyl groups (including the primary alcohol) that are susceptible to cleavage. Specifically,the $C_2, C_3, C_4$ and $C_5$ positions with $OH$ groups allow for the consumption of $3$ moles of $HIO_4$. For structure $Y$: The structure has two adjacent hydroxyl groups available for oxidation,leading to the consumption of $2$ moles of $HIO_4$. Thus,the moles consumed are $3$ and $2$ respectively. Therefore,the correct option is $(d)$.

The structures of cyclic $D$-glucoside are given. Determine the moles of $HIO_4$ consumed by $X$ and $Y$ respectively.
