Stereochemistry refers to the three dimensional arrangement of atoms in molecules, especially those aspects that go beyond the connectivity (which atoms are connected to each other) captured in a Lewis structure. Two molecules that are mirror images of each other (enantiomers) differ in stereochemistry. Another common example are cis and trans double bonds, such as in fatty acids. | [[Image:Chirality.jpg|right]]Stereochemistry refers to the three dimensional arrangement of atoms in molecules, especially those aspects that go beyond the connectivity (which atoms are connected to each other) captured in a Lewis structure.

You can rotate the left and the right molecule by dragging them. Try rotating the right molecule so that is looks exactly the same as the left molecule. Or imagine a mirror between the two molecules, and rotate them that the same atoms are on top and on the bottom, but left and right is reversed. | You can rotate the left and the right molecule by dragging them.
