chirality

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 = S 2, a rotation-reflection axis, S 2n). If the object is superposable on its mirror image the object is described as being achiral.
