WebThe definition of chirality is the property of any object (molecule) being non-superimposable on its mirror image. The left and right hand are mirror images of each other, and they are not superimposable, so both the left hand and right hand are chiral. You can also find many other objects in daily life that show chirality as well. 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 mirror image of an achiral obj…

Webchi·ral·i·ty. (kī-răl′ĭ-tē) n. The aspect of a structure or property, such as the configuration of a molecule or the spin of a particle, that renders that structure or property distinguishable from its mirror image or symmetrical opposite. Also called handedness. WebChirality is tied conceptually to the idea of asymmetry, and any molecule that has a plane of symmetry cannot be chiral. When looking for a plane of symmetry, however, we must consider all possible conformations that a molecule could adopt. dictionary enjoin
