Show hintHide hint
Consider how many ligands are necessary for each geometry.
Question 5.
Describe how the geometry changes when a hexacoordinate complex is formed as opposed to a tetracoordinate complex. Provide examples.
Show hintHide hint
Consider how the number of ligands affects spatial arrangement around the central atom.
Question 6.
Explain the concept of ligand field theory in relation to the geometry of coordination complexes and how it influences the color of the complexes.
Show hintHide hint
Think about how the colors seen in coordination compounds can correspond to the nature of d-orbitals involved.
