WebbPi bonds are chemical bonds that are covalent in nature and involve the lateral overlapping of two lobes of an atomic orbital with two lobes of another atomic orbital that belongs to a different atom. Pi bonds are often written as ‘𝛑 bonds’, where the Greek letter ‘𝛑’ refers to the similar symmetry of the pi bond and the p orbital. WebbFigure 5.23 In the ethene molecule, C 2 H 4, there are (a) five σ bonds. One C–C σ bond results from overlap of sp 2 hybrid orbitals on the carbon atom with one sp 2 hybrid orbital on the other carbon atom. Four C–H bonds result from the overlap between the C atoms' sp 2 orbitals with s orbitals on the hydrogen atoms. (b) The π bond is formed by the side-by …

A pi bond (π 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.
