Werner's Theory and Primary Valences

Werner's theory explains the coordination compounds based on the concept of primary and secondary valences. The primary valence is the oxidation state of the central metal atom, which is equal to the charge on the central metal ion. The primary valence is satisfied by negative ions or neutral molecules that coordinate with the central metal ion.

Importance of Primary Valences

The primary valence plays a crucial role in determining the geometry of the complex. The coordination number of the central metal atom is equal to the number of ligands coordinating with the central metal ion. The coordination number and the geometry of the complex depend on the primary valence and the number of primary valences present in the central metal ion.

Coordination Number and Geometry

The coordination number and the geometry of the complex depend on the number of primary valences present in the central metal ion. For example, if the central metal ion has two primary valences, it can form two types of bonds, and the coordination number is two. The geometry of the complex is linear.

On the other hand, if the central metal ion has four primary valences, it can form four types of bonds, and the coordination number is four. The geometry of the complex is tetrahedral. Thus, the primary valences of the central metal ion play a crucial role in determining the coordination number and the geometry of the complex.

Conclusion

In conclusion, Werner's theory explains the coordination compounds based on the concept of primary and secondary valences. The primary valence of the central metal ion is equal to its oxidation state and is satisfied by negative ions or neutral molecules that coordinate with the central metal ion. The primary valences of the central metal ion determine the coordination number and the geometry of the complex.
