The Asymmetric Carbon Atom Revisited
In this chapter, we illustrate our general approach to stereochemical problems, and the use of the concepts developed in the previous chapter, by studying the asymmetric carbon atom : we first determine its chemical identity group, and then find that the group is compatible with the usual tetrahedral valence skeleton. It will be pointed out that even in the case of this molecule, which can be represented by a simple geometric model, a purely geometric view of its stereochemical features has inherent logical difficulties, and that these difficulties disappear when the chemical identity viewpoint is adopted.
