Notes on this chapter's pedagogy

Chapter 21 develops the canonical reaction of aromatic compounds: electrophilic aromatic substitution (EAS). The key insight: aromatics substitute rather than add (preserves aromaticity). The mechanism is a two-step electrophile-attack-then-deprotonate cycle.

The chapter develops: 1. The mechanism (electrophile + arenium ion + deprotonation). 2. Five major EAS reactions (halogenation, nitration, sulfonation, FC alkylation, FC acylation). 3. Limitations of FC alkylation (rearrangement, polyalkylation, deactivated rings). 4. The acylation + reduction strategy for installing linear alkyl groups. 5. Industrial applications (ibuprofen, TNT, nitrobenzene, cumene). 6. Other EAS reactions (Vilsmeier, Reimer-Tiemann, Kolbe-Schmitt).

Chapter 22 covers substituent effects — how existing groups direct further EAS to ortho/para or meta. This is the natural follow-up to Ch 21's mechanism.
