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. WebAug 26, 2024 · 1. The ligand field causes the splitting of d orbitals of the central metal atom into two sets (t 2g and eg). 2. When the white light falls on the complex ion, the central metal ion absorbs visible light corresponding to the crystal field splitting energy and transmits rest of the light which is responsible for the colour of the complex. 3.

What is Crystal Field Theory? - Vedantu

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. 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, … crypto custody business
