In the presence of hot alkaline potassium permanganate solution 2-butene will give
Correct answer: C. Two moles ethanoic acid
- A. Formic acid + acetic acid
- B. Two moles of methanoic acid
- C. Two moles ethanoic acid
- D. Ethylene glycol
Explanation
C4H8 + 2 KMnO4 + 3 H2O -> 2 CH3COOH + 2 MnO2 + 2 KOH + 2 H2O. From the above reaction, we understand that 2 moles of butene produce 2 moles of ethanoic acid. Therefore option C is correct.

About Aldehydes and Ketones
Aldehydes and ketones contain the polar carbonyl group, but aldehydes are generally more readily oxidised and more reactive than ketones. Coverage includes preparation by oxidation or reduction routes, nucleophilic addition of reagents such as hydrogen cyanide and bisulfite, and tests that distinguish aldehydes from ketones.
