Question

valence bond theory​

Answer 1

Explanation:

Valence bond (VB) theory is a chemical bonding theory that explains the chemical bonding between two atoms. ... The two atoms share each other's unpaired electron to form a filled orbital to form a hybrid orbital and bond together.

Answer 2

Info on 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.
