Answer:

The important postulates of Werner's theory are: The central metal or the metal atoms in coordination compounds show two types of valency. ... It means that the coordination number is fixed. The metal atom works towards satisfying both its primary and secondary valencies. A negative ion satisfies the primary valency.

The theory fails to correlate the bonding and spatial arrangement of ions, atoms or molecules in a co-ordination compound with respect of the electronic configuration of the central metal atom. The theory does not give an explanation regarding the colour and magnetic properties of co-ordination compounds
