Question
CH3– CH2– OH 4Alkaline KMnO Heat+ → CH3 – COOHIn the above given reaction, alkaline KMnO4 acts as(a) reducing agent(b) oxidising agent(c) catalyst(d) dehydrating agen
Solution
In the given reaction, alkaline KMnO4 (Potassium permanganate) acts as an (b) oxidising agent.
Here's why:
The reaction is an oxidation reaction where ethanol (CH3– CH2– OH) is being oxidized to acetic acid (CH3 – COOH). In this process, the ethanol loses hydrogen atoms, which is a characteristic of oxidation reactions.
The substance that gains these electrons (or in this case, causes another substance to lose electrons/hydrogen atoms) is called an oxidizing agent. In this reaction, that's the role of the alkaline KMnO4. It facilitates the oxidation of ethanol to acetic acid.
So, the correct answer is (b) oxidising agent.
