Stereochemistry
In Chapters 1–3, we discussed electron distribution in organic molecules. In
this chapter, we discuss the 3D structure of organic compounds.1 The structure
may be such that stereoisomerism2 is possible. Stereoisomers are compounds
made up of the same atoms bonded by the same sequence of bonds, but having
different 3D structures that are not interchangeable. These 3D structures are
called configurations.
