In a complex, the central metal atom or ion is surrounded by various ligands which are either negatively charged ions (F-,CI-,CN-, etc) or neutral molecules (H2O,NH3, en, etc.) and the most electronegative atom in them points towards central metal ion. 2.
WebQ1. Explain the bonding in coordination compounds in terms of Werner’s postulates. Answer: ( a ) A metal shows two kinds of valencies viz primary valency and secondary valency. Negative ions satisfy primary valencies, …
WebAug 26, 2024 · Best answer 1. Crystal field theory assumes that the bond between the ligand and the central metal atom is purely ionic, i.e., the bond is framed due to the electrostatic attraction between the electron rich ligand and electron deficient metal. 2. WebCrystal field theory received considerable support from the coordination chemists and hence it replaced the valence bond theory. Crystal field theory is based on the assumption that the interaction between the metal ions and the ligands is purely electrostatic in nature.
WebQuestion What is crystal field splitting energy? How does the magnitude of Δ 0 decide the actual configuration of d orbitals in a coordination entity? Hard Solution Verified by Toppr The crystal field stabilisation energy (CFSE) is the gain in the energy achieved by preferential filling up of orbitals by electrons.
