Lesson 1 - Introducing Benzene 1) The comparison of the Kekulé model of benzene with the subsequent delocalised models for benzene in terms of p-orbital overlap forming a delocalised π-system 2) The experimental evidence for a delocalised, rather than Kekulé, model for benzene in terms of bond lengths, enthalpy change of hydrogenation and resistance to reaction 3) Use of IUPAC rules of nomenclature for systematically naming substituted aromatic compounds

Lesson 3 - Electrophilic substitution part 2 Chlorination of Benzene Alklylation reactions Friedel-Crafts Acylation Alkenes vs Arenes
