Differentiate between `VB` theory and Lewis concept.

Text Solution

Verified by Experts

The valence bond approach for the covalent bond formation takes into account the energy states of the bonding atomic orbitals. However, the Lewis concept is silent about the energy. It is based on the electron sharing in the bonding atoms. For the details of Lewis concept, consult section 4.1
For the details of Lewis conceptk, consult section 4.1.
