WebAny point in space that can be used as a mirror to reflect any group on a molecule back through it in the opposite direction and obtain an equivalent group is known as a center of symmetry. A molecule has a center of symmetry when an identical atom is located diametrically opposite and equally away from the center. Example WebSymmetry in Organic Chemistry.
