Alcohols can be formed by alkenes in the presence of _.
Correct answer: A. Dilute KMnO4
- A. Dilute KMnO4
- B. Acidified K2Cr2O7
- C. Acidified CuCl2
- D. Pyridine
Explanation
Alkenes are readily oxidised by cold, dilute, aqueous solution of potassium permanganate (Baeyer's reagent) to give vicinal glycols.

About Alkenes
Alkenes are unsaturated hydrocarbons containing a carbon-carbon double bond with sigma and pi components and restricted rotation. Their reactions include electrophilic addition of hydrogen, halogens, hydrogen halides and water, with Markovnikov orientation, oxidation, combustion and polymerisation, while their preparation commonly involves elimination from alkyl halides or alcohols.
