CAIE A Level Chemistry 9701 · Hydroxy compounds
A student plans to oxidise ethanol to ethanoic acid in the laboratory. Describe the reagents and conditions needed, the type of reaction involved, and how the product is isolated. Include in your answer the oxidation state change at the carbon atom of the alcohol group, and explain why the product is ethanoic acid rather than ethanol.
7 marks, so the mark scheme is looking for about 7 separate creditworthy points. Making the same point twice in different words earns it once.
Describe means: Say what happens or what something is like, in order and with detail. You are not being asked why. If there is data, quote it: name the trend, then give figures with units at the points where it changes.
