Now, look at the structures of D -glucose … WebIt stood to reason that a chiral molecule is one that does not contain a plane of symmetry, and thus cannot be superimposed on its mirror image. We now know that chiral molecules contain one or more chiral centers, which are almost always tetrahedral (sp 3-hybridized) carbons with four different substituents. Consider the cartoon molecule A ...
