WebFeb 14, 2024 · Drawing chair conformation of cyclohexane. Follow the following 5 steps to draw the chair form of a cyclohexane ring. Draw two parallel lines slanting down, separated by about half of their length, and the bottom line starting from about the middle of the first as shown in Figure \(\PageIndex{8}\). WebCyclohexene is most stable in a half-chair conformation, unlike the preference for a chair form of cyclohexane. One basis for the cyclohexane conformational preference for a chair is that it allows each bond of the ring to adopt a staggered conformation. For cyclohexene, however, the alkene is planar, equivalent to an eclipsed conformation at ...
