Practise showing electron movement unambiguously with curly arrows, lone pairs, dipoles and charges.
Some syntheses use Diels-Alder reactions, which normally involve a diene and an alkene reacting together to form a cyclohexene.
Draw three curly arrows in Fig. 9.4 to complete the mechanism for the Diels-Alder reaction between buta-1,3-diene and ethene.
