Notes on this chapter's pedagogy

Chapter 20 introduces aromaticity as one of the most important organizing concepts in organic chemistry. The chapter develops: 1. The empirical observation: benzene's special stability. 2. Hückel's rule: cyclic + planar + conjugated + 4n+2 π electrons. 3. Heteroaromatics: extending to N, O, S. 4. Aromatic ions: cyclopentadienyl anion, tropylium cation. 5. Polycyclic aromatics: naphthalene, anthracene, graphene. 6. Biological and pharmaceutical relevance.

Chapter 21 turns to electrophilic aromatic substitution — the canonical reaction of aromatic compounds. Chapters 22-23 cover substituent effects and nucleophilic aromatic substitution, completing the aromatic chemistry of Part V.
