Cyclohexan twist

Webskeleton of cyclohexane assumes a nonplanar, “puckered” conformation. The most stable conformation of cyclohexane is shown in Fig. 7.1 (p. 270). In this con-formation of cyclohexane, the carbons do not lie in a single plane; rather, the carbon skele-ton is puckered. This conformation of cyclohexane is called the chair conformation be- WebFigure 4.3a Boat conformation of cyclohexane. The boat conformation comes from partial C-C bond rotations (only flipping one carbon up to convert the chair to a boat) of the chair conformation, and all the carbons still have 109.5º bond angles, so there are no angle strains. However, the hydrogens on the base of the boat are all in eclipsed ...
