quantum theory of covalent bond

In ionic bond the positive ion pulls the electron density of the anion towards itself and brings about polarisation of the anion. This causes the development of some covalent character in ionic bond..

The bond between two unlike atoms, which differ in their affinities for electrons is said to be a polar covalent bond. When a covalent bond is formed between two atoms of different elements, the bonding pair of electrons will lie more tow..

A double covalent bond consists of two pairs of shared electrons. It is formed by the sharing of two pairs of electrons between two atoms. It is actually a combination of two single bonds. It is represented by putting two short lines between the two atoms [=]. Let us t..

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 bonds. It is represented by ..

Sigma Bond ( s ) When the overlap of orbitals of two atoms takes place along the line joining the two nuclei (orbital axis) then the covalent bond formed is called sigma ( s ) bond. These bonds can be formed due to 's-s', 's-p' or 'p-..

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 bonds. It is represented b..

Orbital Representation of Covalent Bonds - Covalent bonds are formed by the overlap of atomic orbitals. As orbitals have different shapes, it is difficult to represent the actual shape of the orbitals on the paper. Hence a pictorial notation is adopted with t..

Let us now understand each type of bond in detail. A single bond consists of one pair of shared electrons. In other words, it is formed by sharing one pair of electrons or two electrons between the atoms, each atom contributing one electron to the bond..
