But-2-ene, , is an alkene. It is oxidised under two different sets of conditions: cold dilute acidified , and hot concentrated acidified . Compare these two oxidation reactions. In your answer, include the reagents and conditions, the organic products formed, and explain how the hot concentrated oxidation can be used to determine the position of the carbon-carbon double bond in an unknown alkene.
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.
