Resonance Energy The difference between the actual energy of the molecule and that of most stable resonating structure is known as Resonance Energy. Let us suppose that a molecule have…
The four sp3 hybrid orbitals are as follows: Ψ 1 = a 1 ф s + b 1 ф py +d 1 ф pz Ψ 2 = a 2 фs…
Bond order is given by Bond order = /2 Bond order is directly proportional to bond dissociation energy and inversely proportional to bond length i.e. higher the bond order, larger…
HOMO : The highest occupied molecular orbital LOMO : Lowest unoccupied molecular orbital. The term Band gap means the difference between energies of the HOMO and LUMO. It will also…
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…
