Vedclass · Answer

(D) Step $1$: Acid-catalyzed dehydration of the starting alcohol leads to the formation of a carbocation,which then undergoes rearrangement and elimination to form the diene $P$ (a decalin derivative with two double bonds).Step $2$: The diene $P$ reacts with aqueous dilute $KMnO_4$ (Baeyer's reagent) at $0^{\circ}C$. This reagent performs syn-dihydroxylation of double bonds.Step $3$: Since $P$ has two double bonds,both are converted into diols. The resulting product $Q$ contains four hydroxyl groups (two from each double bond).Thus,the number of hydroxyl groups in $Q$ is $4$.

The number of hydroxyl group$(s)$ in $Q$ is
