WebIsomers. How atoms are placed within organic molecules (three-dimensional structure/chemical bonds) determines the overall function of the molecule. Interestingly, some molecules can have the exact same number and types of atoms (i.e., chemical formula) but those atoms can be arranged completely differently, dramatically changing … WebChirality. Chirality / kaɪˈrælɪtiː / is a property of asymmetry important in several branches of science. The word chirality is derived from the Greek χειρ ( kheir ), "hand", a familiar chiral object. An object or a system is chiral if it is distinguishable from its mirror image; that is, it cannot be superimposed onto it.
