Goals: 10

Crystal Field Theory: donors

• Determine the hybridization of an atom based on a Kekulé structure of a molecule
• Describe the limitations of the hybridization model especially as the limitation relates to transition metals

Goals: 10

Ligand Field Theory: donors

• Describe the interactions that lead to bonding between metals and ligands
• Describe the effect the interactions have on the primarily metal-based molecular orbitals
• Describe the effect the interactions have on the primarily ligand-based molecular orbitals
• Use a character table to determine the irreducible representations of group orbitals for ligands that are-donors
