Question

VALENCE BONd theory​

Answer 1

Valence Bond theory describes covalent bond formation as well as the electronic structure of molecules. The theory assumes that electrons occupy atomic orbitals of individual atoms within a molecule, and that the electrons of one atom are attracted to the nucleus of another atom.

Answer 2

Answer:

Valency Bond theory :-

1. Electrons present in the molecule are localised as if they are in isolated atoms.

2.The Atomic orbitals of the combining atoms retain their individual identity.

3. It involves only the increase in the electron density in the region of orbital overlap.

4.The number of covalent bonds formed is equal to the number of combining orbitals.

5.This theory doesn't help in predicting the paramagnetic or diamagnetic behaviour of molecules.

6. It is easy to apply.

7. In this theory resonance is considered.
