WebA molecule's chirality can be determined by several overlapping conditions. Here are two examples of molecules with differing chirality, achiral and chiral. A chiral molecule is distinguished by the presence of two atoms of the same element. If one creates a bisecting plane through the other two atoms, the images on either side are the same.
