20.5.1 :Deduce reaction pathways given the starting
materials and the product. Conversions with more than two stages will not
be assessed. Reagents, conditions and equations should be included. For
example the conversion of 1-bromopropane to 1-butylamine can be done in
two stages: 1-bromopropane can be reacted with potassium cyanide to form
propanenitrile, which can then be reduced by heating with with hydrogen
and a nickel catalyst.
