WebSo this is interesting, and we saw this when we first learned about chirality. Even though we have two chiral centers, this is not a chiral molecule. It is the same thing as its mirror image. It is superimposable on its mirror image. It is superimposable on its mirror image. So even though it has chiral carbons in it, it is not a chiral molecule. 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).
