WebOne of the most interesting types of isomer is mirror-image stereoisomers, a non-superimposable set of two molecules that are mirror images of one another. The 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 ...
