✓ Answer: D Ethanoic acid
The reaction provided is the oxidation of ethanol CH3CH2OH using strong oxidizing agents (alkaline potassium permanganate or acidified potassium dichromate and heat). Ethanoic acid (CH3COOH) is produced in the reaction. Ethanol is a primary alcohol with two carbon atoms while alkaline potassium or acidified potassium dichromate act as strong oxidising agents. Strong oxidation of a primary alcohol yields a carboxylic acid with the same number of carbon atoms.
