pi bonds

[andrea guzman 1F]

If two atoms in a pi bond rotate then the pi bond breaks, what could cause the pi bond to break?

[Katie L 2I]

If you rotate the atoms by themselves (one atom without the other), you will instantly break the pi bond, as the orbitals are no longer overlapping.

[Miguel Hernandez LEC 3]

A pi bond will break when the atoms involved in the bond rotate. This is primarily because when the atoms rotate, the orbitals that make up the bond are no longer overlapping.

A pi bond results during a double bond. pi bonds do not allow free rotation around a bond axis, so all atoms are in one plane. Sigma bonds on the other hand have symmetry around the axis, so they are able to rotate freely.
