What are four important reactions involving benzene?
• Halogenation • In the presence of a Lewis acid catalyst: Figure 46.5: Benzene reactions: Halogenation. • Nitration • In the presence of nitric acid, sulfuric acid, and heat: Figure 46.6: Benzene reactions: Nitration. • Sulfonation • In the presence of fuming sulfuric acid: Figure 46.7: Benzene reactions: Sulfonation. • Friedel-Crafts acylation: Figure 46.8: Friedel-Crafts acylation: Addition of the acyl group to benzene and the formation of a halide acid.
