What is the difference between Valence bond theory and hybridisation?

6 years ago


Answers : (1)


Dear deeksha,

Valence bond theory describes a chemical bond as the overlap of atomic orbitals. In the case of the hydrogen molecule, the 1s orbital of one hydrogen atom overlaps with the 1s orbital of the second hydrogen atom to form a molecular orbital called a sigma bond. Attraction increases as the distance between the atoms gets closer but nuclear-nuclear repulsion becomes important if the atoms approach too close.

And hybridisation is the mixing of atomic orbitals to form new orbitals suitable for bonding.
