Baeyer strain theory

Baeyer strain theory (Section 3 4) Incorrect nineteenth century theory that considered the nngs of cycloalkanes to be planar and assessed their stabilities according to how much the angles of a corresponding regular polygon devi ated from the tetrahedral value of 109 5°... 

The Baeyer strain theory is useful to us in identifying angle strain as a destabilizing effect. Its fundfflnental flaw is its assumption that the rings of cycloalkanes are planar-. With the exception of cyclopropane, cycloalkanes are nonplanar. Sections 3.5-3.13 describe the shapes of cycloalkanes. We ll begin with cyclopropane.

It is of historical interest to note that the Baeyer strain theory with its planar rings predicts only one form of decalin with the ring-junction hydrogens on the same side of the molecule (Figure 12-23). The Sachse-Mohr concept of puckered strain-free rings allows for two isomers. In fact, Mohr predicted that the two isomers of decalin should exist before W. Hiickel (1925) succeeded in preparing them. Both isomers occur in petroleum.
