### Sigma vs Pi Bonds

Can someone explain the difference between sigma and pi bonds and how they relate to resonance?

### Re: Sigma vs Pi Bonds

A sigma bond ( σ bond) is a bond formed by the overlap of orbitals in an end-to-end fashion, with the electron density concentrated between the nuclei of the bonding atoms. A pi bond ( π bond) is a bond formed by the overlap of orbitals in a side-by-side fashion with the electron density concentrated above and below the plane of the nuclei of the bonding atoms.
