2. Main Points The electron waves Crystal structure
Molecular Orbital Theory & Ligand Field Theory
Lewis acids and bases
Everything besides organic carbon
Organometallics & Catalysis
Isomerism

3. The Electron Cloud Electron wave nature  radial wave function
Electron density plot
Angular wave function  s, p, d orbitals
3D probability plots

4. Crystal Structure Ionic and metallic bonding
Cubic (face centered) & hexagonal close packing (ABA vs. ABC)
Simple cubic & body-centered cubic
Dependent on ionic radii

5. Molecular Orbital Theory
Bonding theory that uses guidelines of electron cloud shape and energy to determine bonding
Bonding
Nonbonding
Antibonding

6. Ligand Field Theory MO theory applied to d-block metals
d-orbitals split into t2g (dxy, dyz, dxz) and eg (dz2 and dx2-y2) sets
Δoct

7. Lewis Acids and Bases Brønsted acid: electron pair acceptor
Brønsted base: electron pair donor
Hard/soft acid/bases
Hard: small, densely charged
Soft: large, polarizable

8. Everything Besides Organic Carbon
s & p block
Octet rule
Hydrides, oxides, halides
Noble gases: “Everyone said, ‘Noble gases don’t react,’ until some idiot tried and it and found that they did.”
Mostly halides (XeF6)
d block
18 electron rule
Oxidation states
Geometries: tetrahedral, octahedral

9. Transition Metal Complexes
Sigma and pi donors
Pi acceptors
Classical Coordination Complexes and Organometallic Complexes
Reactions: substitution and redox
Electron transfer

10. Band Theory
Explains TM properties of conduction, luster, malleability and ductility
Delocalized electrons flow freely between bonding and antibonding bands

11. Organometallics Mostly aromatic compounds (sandwiches) and carbonyls
Hapticity (η)
π-acceptors/donors
Catalysis
Reduce alkenes and alkynes to alkanes using platinum
Industrial processes
Ethene to acetone using PdCl4

12. Isomerism
