Achiral compounds with more than one stereogenic centre - Meso

The 3D structures above on the left and on the right of the screen are exactly the same. They are NOT enantiomers.

Prove this to yourself by clicking on the 2D structure on the left of the page below, then on the arrows to see how the 3D molecule rotates to make it superimposable on the right hand 3D structure. Thus this compound is not chiral.

Click the structures and arrows to view the 3D models and animations respectively

Compounds that contain more than one stereogenic centre but are also achiral are described as

meso compounds.
