3D stereo pairs: Benzene Ring with pi orbitals

To see the stereo effect, please gaze at infinity at a point between the two images. You should eventually see three images. The middle image will be a combination of the left and right images and it should look solid (stereo or 3d). The effect can sometimes be improved by holding a sheet of paper or card perpendicular to the image pair so that your left eye only sees the left image and your right eye only sees the right image. To focus, move your head closer to or further from the image. It might take a few tries to achieve the effect.

benzene C₆H₆: consists of six carbon atoms arranged in a ring in the form of a regular hexagon. From each carbon atom (black spheres drawn at the covalent radius of carbon) projects a hydrogen atom (green spheres drawn at the covalent radius of hydrogen). The carbon and hydrogen atoms all lie in the same plane. It is an aromatic hydrocarbon (or arene). Delocalized electrons exist above and below the plane of the ring (shown as a red cloud above and below the benzene ring). These are the pi (π) electrons from the π orbitals. Benzene is carcinogenic.
