4.3 – Aromaticity
Learning Objectives
- Use the criteria for aromaticity to determine whether a compound is aromatic or non-aromatic, including neutral, cationic, and anionic compounds, as well as heterocyclic compounds.
- Use valence bond theory to explain the hybridization of atoms and where the electrons are located in an aromatic compound.
- Draw resonance structures of aromatic compounds, using the appropriate chemical arrows.
- Explain how electron delocalization stabilizes aromatic rings, and how this impacts their reactivity.
- Describe applications of aromaticity in DNA bases and other systems.
