Comprehensive A2 Level Chemistry notes on Arenes, covering bonding in benzene, its properties, and nomenclature of aromatic compounds. Explains electrophilic substitution mechanisms with reactions including halogenation, nitration, alkylation, and acylation. Also covers electrophilic addition (hydrogenation), side-chain reactions (free radical substitution and oxidation to benzoic acid), and effects of ring-activating and deactivating groups. Essential for mastering aromatic chemistry and exam preparation.
