Question 1

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

πŸ’‘ Hint: Think about how the presence of ligands affects d orbitals.

Question 2

True or False: Strong field ligands always result in a high-spin configuration.

  • True
  • False

πŸ’‘ Hint: Consider the relationship between field strength and electron arrangement.

Question 1

Predict the colors and magnetic behavior of the complexes [Co(Hβ‚‚O)₆]²⁺ and [Co(CN)₆]³⁻.

πŸ’‘ Hint: Consider how the ligand strength influences electron pairing and optical properties.

Question 2

Calculate the expected LFSE for a complex with strong-field ligands if Ξ”_oct = 2.0 eV. What would the impact be on oxidation state stability?

πŸ’‘ Hint: Use the provided formulas for calculating LFSE in octahedral complexes and analyze how LFSE influences the choice of oxidation states.
