5 Common Structures with Formal Charges C C Carbon Nitrogen N N N Oxygen O O Halogens X N N N O (Formal Charge = # valence e - - # of bonds - # of non-bonding e - (lone pairs)) Molecular Orbital Theory Use all Atomic Orbitals to build Molecular Orbitals Involves delocalized electrons Can be used to describe reactions – Highest Occupied Molecular Orbital (HOMO) and Lowest Unoccupied Molecular Orbital (LUMO) A different approach compared with Valence Bond Theory, which uses localized hybrid orbitals. mix first, then bond
