WebJan 3, 2015 · A molecule is considered chiral if there exists another molecule that is of identical composition but which is arranged in a non-superposable mirror image. Also the presence of an asymmetric carbon atom is often the feature that causes chirality in molecules. Two mirror images of a chiral molecule are called enantiomers or optical … WebChirality and Symmetry. All objects may be classified with respect to a property we call chirality (from the Greek cheir meaning hand). A chiral object is not identical in all respects (i.e. superimposable) with its mirror image. An achiral object is identical with (superimposable on) its mirror image. Chiral objects have a "handedness", for example, …
