Ethylbenzene on being treated with alkaline KMnO4 or acidified KMnO4  gives benzoic.

Answer 2

Answer: The conversion is given below:

Explanation:

We are given to convert ethylbenzene to benzoic acid.

For this conversion, we do the direct oxidation of ethyl benzne with the help of alkaline potassium permanganate $(KMnO_4)$ or acidified potassium chromate $K_2Cr_2O_7$. This results to the formation of benzoic acid.

The equation for the above conversion is attached in the image below.
