Question 1.
What does Crystal Field Theory explain?
Show hintHide hint
Think about the interaction between ligands and metal ions.
Question 2.
Name a strong field ligand.
Show hintHide hint
Consider ligands that create a large splitting in d orbitals.
3Question 3.
What does the term Ligand Field Stabilization Energy (LFSE) refer to?
- Energy gained by electrons in higher d orbitals
- Energy difference between d orbitals in the presence of a ligand field
- Energy lost when ligands are removed
Show hintHide hint
Think about how the presence of ligands affects d orbitals.
4Question 4.
True or False: Strong field ligands always result in a high-spin configuration.
- True
- False
Show hintHide hint
Consider the relationship between field strength and electron arrangement.
Question 5.
Predict the colors and magnetic behavior of the complexes [Co(H₂O)₆]²⁺ and [Co(CN)₆]³⁻.
Show hintHide hint
Consider how the ligand strength influences electron pairing and optical properties.
Question 6.
Calculate the expected LFSE for a complex with strong-field ligands if Δ_oct = 2.0 eV. What would the impact be on oxidation state stability?
Show hintHide hint
Use the provided formulas for calculating LFSE in octahedral complexes and analyze how LFSE influences the choice of oxidation states.
