Rotating Pi bonds

Is there any time that a pi bond can rotate or does it break when it begins to rotate?

A pi-bond will break when it starts to rotate. I don't think there is a situation where it can rotate.

Pi bonds break if they are rotated. This is due to their rigidness and the way that they are bonded side by side, different than sigma bonds.

I also agree with the answers above!

Pi bonds cannot rotate the same way as sigma bonds do since the rotation would break the pi bond interaction. Compared to pi bonds which have their electron density above and below the bond axis (bonding sideways), sigma bonds have their electron density along the bond axis. This allows sigma bonds to rotate.
