Answer: Hybridisation of metal orbitals and geometry; doesn't explain colour or magnetism well.
- A Hybridisation of metal orbitals and geometry; doesn't explain colour or magnetism well
- B Every property of the complex, including its colour and magnetism in full detail
- C Mainly the magnetic behaviour of the complex and nothing else as frequently observed in practice
- D Mainly the kinetics and reaction rates of the complex's ligand exchange in many documented cases
Correct answer: A. Hybridisation of metal orbitals and geometry; doesn't explain colour or magnetism well
Explanation: VBT explains shape and hybridisation of complexes but fails to satisfactorily explain colour (d-d transitions) and paramagnetism in a quantitative way.
The three common coordination geometries: octahedral (6 ligands), tetrahedral (4 ligands), and square planar (4 ligands in one plane).
Concept context
Study of compounds where a central metal atom is bonded to surrounding ligands. Covers nomenclature, types of isomerism, bonding theories (VBT, CFT), and applications in medicine, photography, and industry.
