double bondZoomA-Z

Subject - Organic Chemistry

The double bond, a special case of a covalent bond, is formed from two electron pairs and consists of one σ and one π bond. The stronger σ bond is generated by the overlap of two sp2 hybrid orbitals, while the weaker π bond is formed by overlap of two p bonds.

In chemical graphics, two parallel lines between the bonding atoms represent a double bond.

Polar double bonds are generated if the bonding atoms show different electronegativities.

Double bonds joining at least three continuous carbon atoms are called cumulative double bonds .

Double bonds alternating with single bonds in molecules are named conjugated double bonds.
