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, … WebSep 2, 2024 · It is chiral, meaning that it can exist as two molecular structures that are non-superimposable mirror images of each other—just like a right hand and a left hand. It is also a very flexible and...
WebChirality 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 … WebThe existence of these molecules is determined by concept known as chirality. The word “chiral” was derived from the Greek word for hand, because our hands are good example of chirality since they are non-superimposable mirror images of each other. ...
