Answer and explanation

Correct answer: Ethanoic acid

Alkaline potassium permanganate is a strong oxidising agent. It oxidises the primary alcohol ethanol to ethanoic acid: \(\mathrm{CH_3CH_2OH + 2[O] \rightarrow CH_3COOH + H_2O}\). Ethanal can be an intermediate product, but further oxidation gives ethanoic acid.
