WebChirality is an important geometric property relating to a molecule's symmetry. A chiral molecule is non-superimposable with its mirror image, and has a "handedness" (think of shoes, which specifically go with a right or left foot). An achiral molecule is superimposable with its mirror image and do not have "handedness" (think of a baseball bat ... WebNov 3, 2024 · Chirality. 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).
