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.
A single bond is usually a Ï bond. Pi (Ï) bonds are weaker and are due to lateral overlap between p (or d) orbitals. A double bond between two given atoms consists of one Ï and one Ï bond, and a triple bond is one Ï and two Ï bonds. Covalent bonds are also affected by the electronegativity of the connected atoms which determines the chemical polarity of the bond.
