CAIE A Level Chemistry 9701 · Nitrogen compounds
Compare the formation of a nitrile from a halogenoalkane with the formation of a hydroxynitrile from an aldehyde. In your answer, include the reagents and conditions used in each case, and the functional group(s) present in the organic product. Also outline the conditions required for the hydrolysis of a nitrile to a carboxylic acid, and state whether the outcome differs depending on whether acid or alkali is used.
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.
