The most stable conformation of cyclohexane is the chair form shown to the right. The C-C-C bonds are very close to 109.5 o , so it is almost free of angle strain. In organic chemistry, cyclohexane conformations are any of several three-dimensional shapes adopted by molecules of cyclohexane. Because many compounds feature structurally similar six-membered rings, the structure and dynamics of cyclohexane are important prototypes of a wide range of compounds.
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- Webflexibility of the cyclohexane ring.
