WebChirality in molecules devoid of chiral centers occurs in both natural and synthetic substances, which have enormous importance as ligands in asymmetric catalysis, and some exhibit biological activity (e.g., the antifertility agent gossypol, Figure 22.2).Molecules belonging to this class of stereoisomers include biphenyls, allenes, spiranes, helicenes, … WebChirality (physics) A chiral phenomenon is one that is not identical to its mirror image (see the article on mathematical chirality ). The spin of a particle may be used to define a handedness, or helicity, for that particle, which, in the case of a massless particle, is the same as chirality. A symmetry transformation between the two is called ...
