Question

On the basis of valence bond theory explain the nature of bonding in the [CoF₆]³⁻

Answer 1

Explanation:

I do not know answer of this question

Answer 2

There is WEAK Ligand Field in Structure

Explanation:

The oxidation state of cobalt in this complex is +3, so we have  

The Structure is attached..

• F^- ion provides a weak ligand field and unable to pair up the unpaired electrons in the 3d orbitals.

• Hence, 6 equivalent hybrid orbitals are obtained by mixing one 4s, 3 4p, and 2 4d orbitals.

• 6 empty $sp^3d^2$ hybrid orbitals are filled up by 6 electron pairs provided by $F^-$ ion.

• The highly para magnetic nature of the complex further confirms the presence of 4 unpaired electrons.

As d-orbitals of the outermost shell take part in hybridization, the complex thus formed are called outer complexes.
