alleryWhen ethanol is warmed with alkaline potassium permanganate, it is oxidised to:
AEthane
BEthene
CEthanoic acid
DSodium ethoxide
Answer & Solution
Correct answer: C. Ethanoic acid
1. Alkaline potassium permanganate is an oxidising agent.
2. It supplies oxygen that acts on the -OH group region of ethanol.
3. Ethanol is converted to ethanoic acid (CH3COOH).
4. Rule out B: ethene is formed by dehydration with conc. H2SO4, not by oxidation.
