Question

Write the points of Werner's co-ordination theory.

Answer 1

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.

Answer 2

Answer:

Some of the important points of Werner's coordination theory are:

1. The central metal atom exhibits two types of valency- the primary ( related to oxidation number)and secondary( related to coordination number).

2. The number of secondary valencies is fixed for each of the metal atoms.

3. The metal atom usually satisfies both primary and secondary valencies.

4. There is a fixed geometry of the coordination compound which is because of the secondary valency. It also determines the stereochemistry of the coordination compounds.
