Question

ethylbenzene react with KMnO4/ KOH in presence of H+ion

Answer 1

Hi, please consider the answer given below;

When ethylbenzene reacts with KMnO4/ KOH in presence of H+ion the product for that reaction is benzoic acid.

This reaction is normally typical when the an alkyl group is attached to the benzene ring and the product formed is normally benzoic acid and this reaction is an oxidation reaction.

H+  ions acts as catalyst in this reaction and the reaction normally takes place in basic medium  and that is the reason why KOH is used.

Answer 2

The oxidation of an alkylbenzene in the presence of potassium permanganate/potassium hydroxide leads to the formation of benzoic acid.

This reaction takes place only when a hydrogen is present on the benzylic carbon

Reaction:

C6H5 ---> C6H5COOH

Ans: benzoic acid
