Questions and Answers

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?

  • 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

    • What is the primary postulate of Werner's coordination theory?

  • Metal ions can exhibit different coordination numbers and geometries
  • Transition metals exhibit variable oxidation states
  • Ligands are attached to a central metal atom through coordinate covalent bonds (correct)
  • A coordination complex consists of a central metal atom bonded to neutral or negatively charged ligands
