What is the product formed when tertiary alcohol is treated with alkaline $KMnO_4$ at elevated temperature?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → A mixture of carboxylic acids
When a tertiary alcohol is treated with alkaline KMnO4 at elevated temperature, it undergoes oxidative cleavage (since it lacks an α-hydrogen).
This cleavage leads to the formation of a mixture of carboxylic acids.
