Chair Conformation. First we must lay the groundwork but introduce what is unique about the chair conformation of cyclohexane. All carbon centers are equivalent.
Six hydrogen centers are poised in axial positions roughly parallel with the c 3 axis. In the chair comformation the internal bond angle at a carbon atom is 111 4º very close to the ideal value 109 5º. I ve seen lots of ways to draw chair conformations and lots of students come up with their own way of doing it so whatever works for you just be consistent and be careful.
Other conformations for cyclohexane do exist and they include the boat half chair and twist boat conformations but the most important conformation is the chair because this conformation is typically the most stable conformation.
The chair conformation is customarily drawn either as 2 or as 3 which are mirror images of each other. First we must lay the groundwork but introduce what is unique about the chair conformation of cyclohexane. Because of this it is often used in organic chemistry. This organic chemistry video tutorial provides a basic introduction into drawing the chair conformation of cyclohexane and identifying the most stable confor.
