2 Assuming you start with 1 g of benzaldehyde work out how much malononitrile
(NCCH2CN) you would need for the reaction. (7 marks) (Assume 1 mole of
benzaldehyde requires 1 mole of malononitrile for the reaction). Work out the mass of
tyrphostin you would get assuming a 100% yield for the reaction (3 marks).
