उत्तर
Postulates of Werner’s theory:
- Postulate (1): Unlike metal salts, the metal in a complex possesses two types of valencies: primary (ionizable) valency and secondary (nonionizable) valency.
- Postulate (2): The ionizable sphere consists of entities which satisfy the primary valency of the metal. Primary valencies are generally satisfied by anions.
- Postulate (3): The secondary coordination sphere consists of entities which satisfy the secondary valencies and are non ionizable. The secondary valencies for a metal ion are fixed and satisfied by either by anions or neutral ligands. Number of secondary valencies is equal to the coordination number
- Postulate (4): The secondary valencies have a fixed spatial arrangement around the metal ion.
