Ethanenitrile, , is reduced by hydrogen in the presence of a nickel catalyst to form a primary amine. State the name and formula of the organic product, and explain, in terms of the structure of the amine, why an aqueous solution of this amine is basic. Your explanation should include an equation for the reaction of the amine with water.
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.
Explain means: Give the reasons or the mechanism: why or how something happens. Link each point to the next with because, so or which means. A list of facts with no links usually loses the reasoning marks.
