Pi Bond Definition


Pi bonds are formed between two adjacent atom's p-orbitals.

Two adjacent atoms with unbonded p-orbital electrons can merge together to form an electron pair. This forms a pi bond.

Definition: A pi bond is a covalent bond formed between two neighboring atom's unbonded p-orbitals.

An unbound p-orbital electron in one atom forms an electron pair with a neighboring atom's unbound, parallel p-orbital electron. This electron pair forms the pi bond.

Double and triple bonds between atoms are usually made up of a single sigma bond and one or two pi bonds. Pi bonds are generally denoted by the Greek letter π.
