Question

Given are the structures of cyclic D-glucoside.

Moles of $Hl{O}_4$ consumed with $X$ and $Y$ are respectively:

• A. $2,2$
• B. $3,3$
• C. $2,3$
• D. $3,2$

Answer 1

The correct option is D $3,2$

$\ast$ Cleavage of alcohol gives carbonyl & cleavage of carbonyl gives acid.

$\ast$ $X$ consumers $3$ moles of ${HIO}_4$ & $Y$ consumes $2$ moles.
