प्रश्न
Why is the conversion of ethanol into ethanoic acid an oxidation reaction?
Advertisements
उत्तर
Ethanol is converted into ethanoic acid by taking up oxygen released by potassium permanganate in the reaction mixture. Since this reaction involves adding oxygen to ethanol, it is an oxidation reaction.
The chemical equation for the above reaction is as follows:
\[\ce{CH3CH2OH + 2[O] -> CH3COOH + H2O}\]
