WebDefinition. When a molecule is chiral, its three-dimensional structure lacks all elements of reflection symmetry. As a consequence, chiral molecules and their nonsuperimposable mirror images (called enantiomers) are distinct compounds. The nonsuperimposable, object–mirror image relationship of our right and left hands is a readily observable ... Chirality /kaɪˈrælɪtiː/ is a property of asymmetry important in several branches of science. The word chirality is derived from the Greek χειρ (kheir), "hand", a familiar chiral object. An object or a system is chiral if it is distinguishable from its mirror image; that is, it cannot be superimposed onto it. Conversely, a … See more In mathematics, a figure is chiral (and said to have chirality) if it cannot be mapped to its mirror image by rotations and translations alone. For example, a right shoe is different from a left shoe, and clockwise is different from … See more A chiral molecule is a type of molecule that has a non-superposable mirror image. The feature that is most often the cause of chirality in molecules is the presence of an asymmetric carbon atom.
