Define the term chirality
WebThis term derives from the Ancient Greek word “cheir” (χείρ) for hand, to give a pictorial sketch of the chirality meaning. In chemistry, molecules that feature chirality can be spatially arranged into two specular, nonsuperimposable structures called enantiomers . Since enantiomeric pairs are the same chemical species, the different ... Webchirality: [ ki-ral´ĭ-te ] the property of handedness, of not being superimposable on a mirror image; the handedness of an asymmetric molecule, as specified by its optical rotation or …

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.
