Pi bonds are covalent bonds in which the electron density is concentrated above and below a plane containing the nuclei of the bonding atoms.

Question

Quizplus · Accepted Answer

Pi bonds are formed by the overlap of atomic orbitals side by side, with the electron density concentrated above and below the plane containing the nuclei of the bonding atoms. This results in a bond that is weaker than a sigma bond (which is formed by the overlap of atomic orbitals end-to-end), and allows for rotation around the bond axis.
