Answer:-
Molecular Orbital (MO) Theory explains how atoms combine to form molecules by merging atomic orbitals into molecular orbitals. These orbitals can be bonding (stabilizing) or antibonding (destabilizing), influencing a molecule’s stability. Electrons fill these orbitals based on energy levels, similar to atomic orbitals. MO theory helps predict magnetic properties, bond strength, and molecular behavior. Unlike valence bond theory, it considers electrons as delocalized over the entire molecule. This theory is essential in quantum chemistry, explaining molecular structures more accurately and aiding in the study of chemical bonding in complex molecules.
