What is the difference between a sigma and a pi bond?

This website has a really good description of the differences and includes diagrams: http://www.majordifferences.com/2014/10 ... gQO1ROPLfY
Basically, a sigma bond is formed by end to end overlapping while a pi bond is formed laterally, with the two p orbitals attaching side by side.

Also, a sigma bond allows the bound atoms to rotate which means the bond has electron density with cylindrical symmetry around the internuclear axis. Pi bonds don't allow bound atoms to rotate and there's electron density above and below the internuclear axis.
