Drawbacks of valence bond theory

WebJan 4, 2024 · According to the Valence Bond theory definition, Electrons in a molecule stay in atomic orbitals instead of molecular orbitals. A covalent bond result from overlapping half-filled atomic orbitals wherein each contains a single electron. These orbitals together yield a pair of shared electrons between the two bonded atoms.
