Question
`"CH"_3 - "CH"_2 - "OH" overset("Alkaline""KMnO"_4 + "Heat")(->) "CH"_3 - "COOH"`
In the above given reaction, alkaline KMnO4 acts as
Options
reducing agent
oxidising agent
catalyst
dehydrating agent

Solution
oxidising agent
Explanation -
In this reaction, alkaline potassium permanganate is adding oxygen to ethanol and hence, oxidising it to acetic acid. Substances that are capable of adding oxygen to others are known as oxidising agents.
