The stereochemistry of the various chemical grouping which constitute the structural units of ring systems is first reviewed. It is then shown that the strain‐free possibilities even of large rings are restricted, and that the ring conformation theoretically derived generally correspond to those found by physical methods. Variations of physical properties and of cyclization yield in homologous series are explained on a conformational basis.
