Web1,3-butadiene is the simplest example of a system of conjugated pi bonds.To be considered conjugated, two or more pi bonds must be separated by only one single bond – in other words, there cannot be an … 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.
