WebSigma bonds are formed by the overlap of orbitals that are pointing directly towards one another. If two atoms are connected by a sigma bond, rotating one of the atoms around the bond axis doesn't break the bond. If a bond between two atoms is broken when one atom is rotated around the bond axis, that bond is called a pi bond. Pi bonds are ... WebDefinition: Sigma (𝜎) Bond . Sigma bonds are covalent bonds that are formed through the head-on or end-to-end overlap of different types of hybridized or unhybridized bonding orbitals.
