WebA pi bond is a covalent bond formed when 2 orbitals overlap sideways . The pi bond is the region above and below a sigma bond where this pair of electrons can be found. When a … WebCount the number of lone pairs + the number of atoms that are directly attached to the central atom. This is the steric number (SN) of the central atom. SN = 4 → sp³. SN = 3 → sp². SN = 2 → sp. For example, the O atom in water (H₂O) has 2 lone pairs and 2 directly attached atoms. ∴ SN = 2 + 2 = 4, and hybridization is sp³.
