I was not satisfied with the synthesis route diagrams provided in the textbooks so I made my own. The poster summaries all the reactions from AS and A2 organic chemistry. Extra versions are provided with some details missing for pupils to fill in. Then a white board quiz allows pupils to practice different reactions and synthesis routes and a card sort allows them to create a large synthesis map from memory. This tried and tested lesson was a hit with my students. Aromatic synthesis lesson to follow.
