WebA molecule is chiral if it cannot be superimposed on its mirror image. A chiral compound will have two enantiomeric forms (a pair of enantiomers). A molecule that contains a plane of symmetry will be superimposable on its mirror image and is thus achiral. Most, but not all chiral molecules contain asymmetric centers (chiral centers).
