CH3 – CH2 – OH (Alkaline KMnO4 + Heat) → CH3 – COOH In the above-given reaction, alkaline KMnO4 acts as (a) reducing agent (b) oxidising agent (c) catalyst (d) dehydrating agent

Answer: (b) oxidising agent

\(CH_{3} + CH_{2}OH \xrightarrow[Heat]{Alkaline\, KMnO_{4}}CH_{3}COOH\)

Alkaline KMnO4 acts as an oxidising agent as it oxidises ethanol to form ethanoic acid. Two Hydrogen atoms are replaced by an atom of oxygen making oxidation of ethanol. Here addition of oxygen is provided by potassium.
