Vedclass · Answer

(C) The reaction of $OsO_4$ with an alkene involves syn-dihydroxylation,where two hydroxyl groups are added to the same face of the double bond. In $3$-cyclohexenol,the existing hydroxyl group at the $1$-position exerts steric hindrance. When $OsO_4$ approaches the double bond,it prefers the face opposite to the bulky $-OH$ group to minimize steric repulsion. Therefore,the major product $(X)$ is the one where the two new $-OH$ groups are added to the face opposite to the existing $-OH$ group,resulting in a cis-triol configuration relative to the new hydroxyls.

The reaction of $3$-cyclohexenol with $OsO_4$ gives two products $X$ and $Y$ in a ratio of $12:1$. The major product $(X)$ is:
