Limitations of vbt theory
NettetMCQs on Valence Bond Theory. Valence Bond Theory was proposed by Heitler and London. It is based on quantum mechanics. It states that the covalent bonds are formed by the overlapping of valence shell atomic orbitals of the two atoms having unpaired electrons. The extent of overlap is a deciding factor of the covalent bond strength. Nettet5. sep. 2024 · The following points will clearly state the limitations of crystal field theory: The assumption that the interaction between metal-ligand is purely electrostatic cannot be said to be very realistic. This theory takes only d-orbitals of a central atom into account. The s and p orbits are not considered for the study.
