What is the basis of valence bond theory discuss how is it different from MO theory?

The main difference between valence bond theory and the molecular orbital theory is that valence bond theory explains the hybridization of orbitals whereas the molecular orbital theory does not give details about the hybridization of orbitals.

What is valence bond theory on the basis of this theory explain directional properties of covalent bond?

Valence bond theory describes the electronic structure of molecules. The theory says that electrons fill the atomic orbitals of an atom within a molecule. It also states that the nucleus of one atom is attracted to the electrons of another atom.

How does valence bond theory explains formation of covalent bond?

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 is meant by MOT theory?

In chemistry, molecular orbital theory (MO theory or MOT) is a method for describing the electronic structure of molecules using quantum mechanics. It was proposed early in the 20th century. Molecular orbital theory and valence bond theory are the foundational theories of quantum chemistry.

What is VBT and MOT?

Valence Bond Theory (VBT) and Molecular Orbital Theory (MOT) have the following common features: 1. The Basic principle is same in both the theories. According to both the theories the energy of overlapping orbitals must be comparable and there must be similarities in their symmetry.

What is the valence bond theory write the rule and limitation of it?

This theory could not explain the perfect geometries of molecule such as Ammonia, Methane, Water etc. This theory did not given perfect bond angle of the molecules like water, CO2, Ammonia etc. Magnetic properties of molecule is not explained in this theory.

What is mot in chemistry?

What are valence bond and covalent bond?

covalent bond: a chemical bond that is formed from the sharing of two electrons between two atoms. valence bond theory: a covalent bond forms between the two atoms by the overlap of half-filled valence atomic orbitals from each atom.
