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 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.
