Question

Select $X$ and $Y$ from the following are respectively:
(where $I:Mn{O}_4^{-}/O{H}^{-}$ and $II:i.HC{O}_{3}H,ii.H_3{O}^{+}$)

• A. $I,II$
• B. $II,I$
• C. $II,II$
• D. $I,I$

Answer 1

The correct option is A $I,II$

Both sets of reagents do dihydroxylation of alkene.
$I:KMn{O}_4/O{H}^{-}\to \text{Syn addition}$
$II:i.HC{O}_{3}H,ii.H_3{O}^{+}\to \text{Anti addition}$.
From the products given, $X$ is $KMn{O}_4/O{H}^{-}$ and $Y$ is $i.HC{O}_{3}H,ii.H_3{O}^{+}$.
