WebChirality roughly translates to “mirror-image, non-superimposable molecules.” A molecule is chiral if its mirrored counterpart exhibits movement in a different direction from the former. A series of overlapped requirements determine whether a molecule is asymmetric or achiral. A chiral molecule is not superimposable on each other.
