Chemistry - CHEMICAL BONDING Question with Solution | TestHub

The Linear Combination of Atomic Orbitals (LCAO) approximation in Molecular Orbital Theory (MOT) requires three main conditions for effective orbital overlap and molecular orbital formation:

1. Atomic orbitals must have comparable energies.

2. Atomic orbitals must have the same symmetry with respect to the molecular axis.

3. Atomic orbitals must overlap to a significant extent.

All these conditions are essential for the formation of stable molecular orbitals.
