In order to explain the properties of electrolysis in solution, Arrhenius proposed the ionic theory. Postulates of Arrhenius theory: When an electrolyte is dissolved in water, its molecules spontaneously split into positively and negatively charged particles called ions. This process is called ‘dissociation’ or ‘ionisation’ i.e.,BA ↔ B- (cation) + A- (anion) In a solution, […]

Molecular orbital theory was proposed by F.Hund and R.S. Mullikan in 1930 which was later developed by Lennard-Jones and Charles Coulson. This theory explains the formation of covalent bonding through entirely different approach, according to this theory atomic orbitals combine to form molecular orbitals. Salient features of molecular orbital theory:1. When atomic orbitals combine, they
