Preferred Label : chirality;
IUPAC definition : The geometric property of a rigid object (or spatial arrangement of points or atoms)
of being non-superposable on its mirror image; such an object has no symmetry elements
of the second kind (a mirror plane, σ S 1, a centre of inversion, i S2, a rotation-reflection
axis, S 2n). If the object is superposable on its mirror image the object is described
as being achiral.;
