Witryna29 lis 2024 · Crystal Field Theory: This theory was developed by Hans Bethe (1929) and John Van Vleck (1932). The main postulates of this theory are-(1) According to this theory there exist an electrostatic force of attraction between the metal ion and ligand i.e. this theory consider the ionic bond between metal ion and ligand. WitrynaThe salient features of this theory are as follows. 1. Crystal Field Theory (CFT) assumes that the bond between the ligand and the central metal atom is purely ionic. i.e. the bond is formed due to the electrostatic attraction between the electron rich ligand and the electron deficient metal. 2. In the coordination compounds, the central metal ... iphone credit card attachment
