Answer 1

Explanation:

According to this theory co-ordinate Bond is formed between the central metal and surrounding legend.

The vacant orbital of the central atom Inter mixed to form new step up orbital called hybrid orbital with hybrid orbital have definite geometry and hence they have a definite geometry to the complex also.

In valence bond theory any one property of complex will be given like magnetic nature or isomerism and we have to find out the hybridization of central atom in the complex.

Answer 2

Answer:

Valence bond theory describes the electronic structure of molecules.

The theory says that electrons fill the atomic orbitals of an atom within a molecule.

★ Strength of covalent bond is based on extent of overlapping

• Overlapping depends on two factors:

1. Nature of orbitals.

2. Nature of overlapping.
