double bond
Two electron pairs
A double bond is a chemical bond in which two atoms share two pairs of electrons, creating a stronger and shorter connection than a single bond.
Double bonds appear in organic chemistry notation as two parallel lines between atoms: The carbon-carbon double bond makes the molecule reactive.
They restrict rotation, giving molecules distinct geometric forms.
