CAIE A Level Chemistry 9701 · Carbonyl compounds
A student oxidises two separate samples of propan-1-ol and propan-2-ol using acidified potassium dichromate() and distillation.
Compare the products formed and the ease of oxidation of these two alcohols. In your answer, name the organic products and state the conditions needed to obtain them.
5 marks, so the mark scheme is looking for about 5 separate creditworthy points. Making the same point twice in different words earns it once.
Compare means: Give similarities or differences between two things, and say which side each point belongs to. Write each point as a pair, for example: A is X, whereas B is Y. Two separate descriptions rarely earn the marks.
