What is the coordination number in coordination compounds?
What is the coordination number in coordination compounds?
- The number of ligands surrounding the central metal atom (correct)
- The total number of atoms directly attached to the metal ion
- The number of bonds formed between the metal ion and the ligands
- The total number of electrons in the d-orbitals of the central metal atom
What is the main limitation of the Valence Bond Theory (VBT) in explaining bonding in transition metal complexes?
What is the main limitation of the Valence Bond Theory (VBT) in explaining bonding in transition metal complexes?
- It cannot explain the color exhibited by transition metal complexes
- It fails to explain the splitting of d-orbitals in a crystal field (correct)
- It doesn't provide a clear explanation for the shapes of coordination complexes
- It does not account for the magnetic properties of transition metal complexes
