उत्तर

When ethanol is oxidised with alkaline potassium permanganate (alkaline KMnO4) or acidified potassium dichromate (acidified K2Cr2O7), ethanoic acid is formed. Alkaline potassium permanganate and acidified potassium dichromate are strong oxidising agents, as they provide oxygen for oxidising other substances in the reaction. This reaction is known as the oxidation reaction.
The chemical equation for the above reaction is as follows:
CH3CH2OH + 2[O] → CH3COOH + H2O
