1-chloropropane reacts with potassium cyanide dissolved in ethanol, with heat, to form a nitrile.
Suggest, in terms of the reaction type and the role of the cyanide ion, why this reaction is useful in organic synthesis. In your answer, name the functional group formed and state the conditions required.
6 marks, so the mark scheme is looking for about 6 separate creditworthy points. Making the same point twice in different words earns it once.
Suggest means: Apply what you know to an unfamiliar situation. There may be more than one acceptable answer. Reason from the principle you have learned to the new context, and say which principle you are using.
