Chirality belongs to the discipline of stereochemistry, which is the study of the 3-dimensional structure of molecules. Chiral compounds are optically active, that means they rotate polarized light to the left or to the right depending on their configuration.
Conversely, an achiral object, such as an atom, is symmetric; its mirror image is not truly opposite, but rather is indistinguishable from the original. In chemistry, chirality usually refers to molecules. Two mirror images of a chiral molecule are called enantiomers or optical isomers.Pairs of enantiomers are often designated as  right-  and left-handed. molecule is achiral (not chiral) when an improper rotation, that is a combination of a rotation and a reflection in a plane, perpendicular to the axis of rotation, results in the same molecule. For tetrahedral molecules, the molecule is chiral if all four substituents are different.
