Differbetween
It is a theory used to describe the formation of different chemical bonds between atoms. This theory explains the overlapping or mixing of atomic orbitals to form chemical bonds. ... The key difference between VBT and CFT is that VBT explains the mixing of orbitals whereas CFT explains the splitting of orbitals.

What is the main difference between VBT mot?
Compare Valence Bond Theory (VBT) and Molecular Orbital Theory (MOT)
| Valence Bond Theory (VBT) | Molecular Orbital Theory (MOT) |
|---|---|
| Bonds are localized to two atoms not molecule. | Bonds are localized to two atoms as well as molecule. |
What is the difference between Vsepr and valence bond theory?
These theories are applied to compounds having covalent bonds. The difference between VSEPR and valence bond theory is that VSEPR theory explains the shape of a molecule whereas valence bond theory explains the creation of chemical bonds between atoms of a molecule.
Why is mot preferred over CFT?
While MO theory is more involved and difficult, it results in a more complete picture of the structure of a chosen molecule. ... CFT successfully accounts for some magnetic properties, colours, hydration enthalpies, and spinel structures of transition metal complexes, but it does not attempt to describe bonding.
What is CFT chemistry?
The Crystal Field Theory (CFT) is a model for the bonding interaction between transition metals and ligands. ... The electrons in the d orbitals of the central metal ion and those in the ligand repel each other due to repulsion between like charges.
What are the postulates of VBT?
Postulates of Valence Bond Theory
- Covalent bonds are formed when two valence orbitals (half-filled) belonging to two different atoms overlap on each other. ...
- The presence of many unpaired electrons in the valence shell of an atom enables it to form multiple bonds with other atoms.
What is VBT and mot?
The valence bond theory (VBT) explains bonding behavior in metals. The molecular orbital theory (MOT) describes bonding behavior in molecules. VBT. Atomic orbitals are mono-centric. Atoms, which are involved in the bond formation, maintain their individual nature.
Can sp3 be bent?
Hybridization and Electron Pair Geometry
For sp3 hybridized central atoms the only possible molecular geometry is tetrahedral. ... If there are only three bonds and one lone pair of electrons holding the place where a bond would be then the shape becomes trigonal pyramidal, 2 bonds and 2 lone pairs the shape is bent.
What are the main points of valence bond theory?
Valence Bond theory describes covalent bond formation as well as the electronic structure of molecules. The theory assumes that electrons occupy atomic orbitals of individual atoms within a molecule, and that the electrons of one atom are attracted to the nucleus of another atom.
What are the limitations of Vsepr theory?
Athough the VSEPR model is useful in predicting molecular geometry, it fails to predict the shapes of isoelectronic species and transition metal compounds. This model does not take relative sizes of substituents and stereochemically inactive lone pairs into account.
Who proposed CFT?
CFT was developed by physicists Hans Bethe and John Hasbrouck van Vleck in the 1930s. CFT was subsequently combined with molecular orbital theory to form the more realistic and complex ligand field theory (LFT), which delivers insight into the process of chemical bonding in transition metal complexes.
What is P in crystal field theory?
This depends on two parameters magnitude of crystal field splitting, Δo and pairing energy, P. The possibilities of two cases can better be explained as: Δo > P – Electron enters in the t2g level giving a configuration of t2g4eg0.
What is crystal field theory 12?
The crystal field theory was proposed by Hans Bethe and VanVleck. This theory gives satisfactory explanation for the bonding and the properties of complexes than the valence bond theory. Assumptions of Crystal field theory: The interaction between the metal ion and the ligand is purely electrostatic.
