sp2 hybridization is a concept in chemistry describing the mixing of one s atomic orbital and two p atomic orbitals to form three degenerate sp2 hybrid orbitals. These hybrid orbitals are arranged in a trigonal planar geometry, with bond angles of approximately 120 degrees. This arrangement maximizes the distance between the electron clouds of the hybrid orbitals, leading to a stable configuration.

The remaining unhybridized p orbital is perpendicular to the plane formed by the sp2 hybrid orbitals. This unhybridized p orbital can participate in pi bonding, forming double or triple bonds with other atoms. For example, in ethene (C2H4), each carbon atom is sp2 hybridized. The sp2 hybrid orbitals on each carbon form sigma bonds with the hydrogen atoms and with each other. The unhybridized p orbitals on adjacent carbon atoms overlap sideways to form a pi bond, resulting in a carbon-carbon double bond.

sp2 hybridization is common in organic molecules containing double bonds, such as alkenes and aromatic compounds. It is also found in some inorganic molecules and ions. The sp2 hybridized atoms are typically planar around the central atom. This type of hybridization influences the molecular geometry, reactivity, and spectroscopic properties of molecules. Understanding sp2 hybridization is crucial for predicting molecular shapes and bonding patterns.
