Two enantiomers of a generic amino acid that is chiral. Chirality /kaÉªËraelÉªtiË/ kaÉªËrÃ¦lÉªtiË is a property of symmetry important in several branches of. Science the word chirality is derived from The, greek (ÏÎµÎ¹Ï), kheir, hand a familiar chiral. objectn object or a system is chiral if it is distinguishable from its mirror image; that is, it cannot be superposed onto it. Conversely, a mirror image of an achiral object, such as a sphere, cannot be distinguished from the object.
Normally, when a tetrahedral atom has four different substituents it is chiral. However, in rare cases, if two of the ligands differ from each other by being mirror images of each other, the mirror image of the molecule is identical to the original, and the molecule is achiral.hirality is important in context of ordered phases as well, for example the addition of a small amount of an optically active molecule to a nematic phase (a phase that has long range orientational order of molecules) transforms that phase to a chiral nematic phase (or cholesteric phase).
