CAIE A Level Chemistry 9701 · Halogen compounds
2-bromobutane is a secondary halogenoalkane. It can react with aqueous sodium hydroxide to form an alcohol, or with ethanolic sodium hydroxide to form an alkene.
Compare these two reactions. In your answer, refer to the reagents and conditions, the type of reaction, and the identity of the organic product formed in each case.
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.
