http://ursula.chem.yale.edu/~chem220/chem220js/STUDYAIDS/isomers/RS14272/axial4.html In chemistry, a molecule or ion is called chiral if it cannot be superposed on its mirror image by any combination of rotations, translations, and some conformational changes. This geometric property is called chirality (/kaɪˈrælɪti/). The terms are derived from Ancient Greek χείρ (cheir) 'hand'; which is the canonical example of an object with this property.

Chirality (from the Greek word cheir, meaning “ hand ”) is the geometric property displayed by any object that is non-superimposable on its mirror image. The main structural feature responsible for chirality is the presence of dissymmetry; as it has no plane of symmetry (as previously explained).
