Hydroxylation of alkene can be carried out by:
Correct answer: A. Alkaline KMnO4
- A. Alkaline KMnO4
- B. O3
- C. H2SO4
- D. K2Cr2O7
Explanation
When alkenes are treated with mild oxidizing reagents like dilute (1%) alkaline KMnO4 solution (Baeyer's Reagent) at low temperature, hydroxylation of double bond occurs resulting in the formation of dihydroxy compounds known as vicinal glycols. The pink colour of KMnO4 solution is discharged during the reaction. It is also a test for the presence of unsaturation in the molecules.

About Chemistry of Hydrocarbons
Hydrocarbons are studied through the structures and reactions of alkanes, alkenes, alkynes and aromatic compounds. Coverage includes free radical substitution in alkanes, electrophilic addition to carbon-carbon multiple bonds, benzene substitution, aromatic stability and the difference between addition reactions of alkenes and substitution reactions of benzene.
