Describe how a primary amine can be prepared from a halogenoalkane and ammonia, and how a secondary amine can be prepared from a halogenoalkane and a primary amine. In each case give the conditions. State the type of reaction occurring. Describe how the basicity of an aqueous solution of a primary amine can be explained in terms of the lone pair on the nitrogen atom.
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.
Describe means: Say what happens or what something is like, in order and with detail. You are not being asked why. If there is data, quote it: name the trend, then give figures with units at the points where it changes.
