quantum theory of covalent bond

The sharing of orbitals between two atoms is possible only when the atoms are close enough to overlap their orbitals. Thus, orbital overlap is necessary for the sharing of electrons and bond formation. With the orbitals coming close together, there is an increase in the electron den..

Ionic Bond Covalent Bond Metallic Bond The transfer of electrons between two atoms having different electro negativities forms this bond. This bond is formed by the mutual sharing of electrons between same or different ..

1) It is a qualitative approach describing bonding in coordination compounds. 2) The theory fails to explain the optical absorption spectra and magnetic properties of coordination compound..

The metal ligand bond arises by donation of pair of electrons by ligands to the central metal ato..

In 1900, Max Planck presented the results of his famous black body radiation experiments, which showed that light has a dual character, behaving like a particle as well as a wave. He gave the Quantum Theory of Radiation explaining electromagnetic radiation and energ..

The following factors favour the formation of covalent bonds..

Comparison Between Single, Double and Triple Covalent Bonds - Single, double and triple covalent bonds differ from each other in the following ways. Single bond is formed by the sharing of one electron pair, (two electrons); a double bond ..

Triple Covalent Bond - A triple covalent bonds consists of three pairs of shared electrons. It is formed by the sharing of three pairs of electrons between two atoms. In all there are six electrons shared between two atoms. It is a combination of three single..
