What are the Reactions of ethanal with potassium permanganate?

Answer 1

Ethanol (CH3CH2OHl) + KMnO4 ----> Ethanal (CH3CHO) -----> Ethanoic Acid (CH3COOH)

Primary Alcohol Oxidized ---> Aldehyde Oxidized---> Carboxyilic Acid

You could attain Ethanal by using the oxidizing agent Pyridinium Chlorochromate (PCC) anhydrously.

Answer 2

A red-ox reaction takes place between these two reagents. Ethanal will oxidize in to ethanoic acid. Permanganate ions will reduce into either to manganese dioxide or manganese +II ions in alkaline and acidic media respectively.

Answer 3

When ethanal reacts with potassium permanganate (KMnO4) in an acidic medium, it is oxidized to ethanoic acid. The purple color of the permanganate solution fades as the reaction proceeds, indicating the reduction of KMnO4 to Mn2+ ions. This is a redox reaction where ethanal is the reducing agent and potassium permanganate is the oxidizing agent.

Answer 4

KMnO4 converts primary alcohol to acid (if with H+) and to aldehyde (if neutral)
