3 full lesson bundle which covers the lessons on aromatic compounds from the AQA A Level Chemistry Specification.

Lesson 1: Benzene and its Structure

1. To describe the Kekulé model of benzene
2. To describe the delocalised model of benzene in terms of P orbital overlap forming a delocalised π system
3. To compare the Kekulé model of benzene and the delocalised model of benzene
4. To explain the experimental evidence which supports the delocalised model of benzene in terms of bond lengths, enthalpy change of hydrogenation and resistance to reaction

Lesson 2: Naming Aromatic Compounds

1. To state the IUPAC name of substituted aromatic compounds
2. To construct the structure of aromatic compounds based on their IUPAC names
3. To analyse the correct numbering system for di and trisubstituted aromatic compounds

Lesson 3: The Reactions of Benzene

1. To understand the electrophilic substitution of aromatic compounds with:

(i) concentrated nitric acid in the presence of concentrated sulfuric acid
(ii) an acyl chloride in the presence of a halogen carrier (Friedel–Crafts reaction) and its importance to synthesis
by formation of a C–C bond to an aromatic ring

1. To construct the mechanism of electrophilic substitution in arenes
