Explain valence bond theory with example
admin 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…
What is Sigma Bond and Sigma Molecular Orbital?
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’…
What do you mean by bonding molecular orbital and anti-bonding molecular orbital?
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) =…
What do you mean by Metallic Bond?
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…
What do you mean by Hydrogen Bond?
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…
What is the importance of hydrogen bonding in sustaining life?
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…
What do you mean by Conjugated Molecule?
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-…
Explain Molecular Orbital Theory.
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…
What are Homonuclear Molecules and Hetero-nuclear Molecules?
Homonuclear molecules Homonuclear molecules are formed from only one element. That is why known as homonuclear. These molecules can consist of various numbers of elements which depends on the properties…
Define Bond Length, Size of the atom and Bond Angle
What is Bond Length? Bond length is the average distance between the centers of the nuclei of two bonded atoms in a molecule. Shorter the bond length, larger is the…
