Question

What does a pi bond look like?

Answer 1

A π bond looks something like two French rolls held closely together along their sides.

Explanation:

Of course, the π bond is really two areas of electron density on either side of a line joining two nuclei, as in the picture below.

The two areas together constitute one π bond, and they are separated by a flat surface (a nodal plane) in which there is no probability of finding an electron.

You can see a computer-generated image of the shape, plus an animation of two `p` orbitals overlapping side-on to form a π orbital at the Orbitron.
