CAIE A Level Chemistry 9701 · Halogen compounds
Compare the production of a halogenoalkane from an alcohol with its production from an alkene. In your answer, refer to the reaction of butan-2-ol with hydrogen bromide gas and to the reaction of but-1-ene with hydrogen bromide gas. Include the conditions required and the structure 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.
