A sigma bond is the end-to-end overlap of the bonding orbitals, usually hybrid orbitals. The sigma bond is a single bond. A pi bond is the side-to-side overlap of unhybridized p-orbitals. A pi bond, along with a sigma bond form a double bond. sigma bond is used in hybridization but pi bond when dealing with saturated molecules is not used,that is double bonds.The oygen molecule is sp hybridized have you ever reasoned or found out why.
By Anne Marie Helmenstine, Ph.D. Definition: Sigma bonds are covalent bonds formed by direct overlapping between two adjacent atom's outermost orbitals. The single electrons from each atom's orbital combine to form an electron pair creating the sigma bond. Sigma bonds are generally denoted by the Greek letter Ï.
