Answer: The extent to which the complex forms in solution (higher Kf = more stable).
- A The extent to which the complex forms in solution (higher Kf = more stable)
- B The specific colour the complex displays once largely formed under usual circumstances
- C The melting point of the solid complex once isolated according to most researchers
- D The overall molecular weight of the formed complex in the majority of cases studied
Correct answer: A. The extent to which the complex forms in solution (higher Kf = more stable)
Explanation: Kf = [complex] / ([metal ion][ligand]<sup>n</sup>); a high Kf means the complex dissociates very little and is very stable.
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.
