WebPlanar chirality, like axial chirality, employs the descriptors P (plus) and M (minus). Chiral molecules having atoms a, b and x lying ina plane and y-z in a plane with atom z orthogonal to the plane fall into this category (Fig. 1). Implicit in this description is that z is restricted from lying in the plane. WebIn fact, 1,3-dimethylcyclopentane has only 2 chiral centres and 3 distinct stereoisomers. Try drawing the molecule out with the two methyl groups trans to one another (both up), you will then notice that there is a centre of symmetry - This "trans" form is a mess compound.
