Chiral definition

Chiral means that the molecules are mirror images of each other and they are not superimposable, i.e., they cannot be placed in the same space in such a way that they will overlap.
Chiral means not coinciding when a specular reflection is imposed; it is applicable to molecules, conformations, and macroscopic objects (e.g., crystals). This term shall also apply to the samples of substances with chiral molecules, even if the macroscopic set of molecules is a racemate;
Chiral means not coinciding when a specular reflection is imposed; it is applicable to molecules, conformations, and macroscopic objects (e.g.,
