The relative energies of molecular orbitals depend upon the following two factors: (i) Atomic orbitals energies for the combination to form molecular orbitals. (ii) The extent of overlapping between the…
Fajan gives the following four rules for the Polarisation: Polarization will be increased by: 1. High charge and small size of the cation. 2. High charge and large size of…
The valence bond theory was developed by W.Heitler and F.London in 1927. Then it was further amended by the Linus Pauling and J.C. Slater. For this Linus Pauling get the…
Sigma bond: sigma bond is formed due to the axial overlapping of two orbital’s (‘s-s’, ‘s-p’or’p-p’). Only one sigma bond can exists between two atoms. Sigma bond is denoted as’…
Bonding Molecular Orbital: Bonding molecular orbital is formed by the addition of overlapping of atomic orbitals. The wave function of the bonding MO may be written as: Ψ (MO) =…
Metallic bond is formed due to the attraction between kernels and the mobile electrons in a metal lattice. Metallic bond is a non-directional bond. This bond is helpful in making…
The bond which is formed between hydrogen atom and a higher electronegative atom (F, O or N) is known as Hydrogen bond. This bond involves dipole to dipole movement. The…
Water is the best example of hydrogen bonding. We all know that how much water is important in our life. So hydrogen bonding is very important for sustaining life. Water…
The linear conjugated polyenes and dienes can be represented by the Free Electron molecular orbital (FEMO). In this p electrons form the pi-bond. Examples of conjugated molecule are: 1, 3-…
Molecular orbital theory was proposed by F. Hund and R.S. Mulliken in 1932.Bonds is localized to two atoms as well as molecule. This theory involves involve distribution of electrons and…
