WebMay 21, 2016 · Chirality is a term that comes to us from the Greek language and is used to describe two objects that may appear identical but when folded over onto themselves they are not symmetrical. Animosity ... WebIn chemistry, axial chirality is a special case of chirality in which a molecule contains two pairs of chemical groups in a non-planar arrangement about an axis of chirality so that the molecule is not superposable on its mirror image. [1] [2] The axis of chirality (or chiral axis) is usually determined by a chemical bond that is constrained ...
