WebAn aldehyde differs from a ketone by having a hydrogen atom attached to the carbonyl group. This makes the aldehydes very easy to oxidise. For example, ethanal, CH 3 CHO, is very easily oxidised to either ethanoic acid, CH 3 COOH, or ethanoate ions, CH 3 COO -. Ketones don't have that hydrogen atom and are resistant to oxidation.
