The total number of compounds from below when treated with hot KMnO4 giving benzoic acid is:
The total number of compounds from below when treated with hot KMnO4 giving benzoic acid is:
Show Hint
- 6
- 3
- 5
- 4
The Correct Option is C
Solution and Explanation
Hot KMnO4 is a strong oxidizing agent that cleaves alkyl side chains attached to benzene rings, converting the alkyl group into a carboxyl group, thus forming benzoic acid.
In the given compounds, the ones with alkyl groups on the benzene ring will be oxidized to benzoic acid.
The number of such compounds that will undergo this transformation is 5.
