R3.4 (AHL) Electron-pair sharing reactions
This large AHL sub-topic covers Lewis acids and bases and the formation of coordination bonds. This is followed by considering the role of nucleophiles in organic substitution reactions, where the rate of the reaction is influenced by the identity of the leaving groups. It then covers the electrophilic addition reactions of alkenes, including an explanation for Markovnikov addition to unsymmetrical alkenes, and...
