Strong field ligands vs weak field ligands, how do they fill? How can you determine the split d orbital delta?
- Strong field: CN- > NO2- > en > NH3. Fill the bottom 3 orbitals first then the top 2 afterward as two different energy levels
- Weak field: H2O > OH- > F- > Cl- > Br- > I-. Fill all 5 orbitals as a single energy level
- Ephoton = hν = hc/λ = Δ split d orbital [using wavelength of max absorption]
