In the planar portion of half chair cyclohexane the C-C bond angles are forced to 120 o which creates significant amounts of angle strain. Also, the corresponding C-H bonds are fully eclipsed which create torsional strain.

Web3.11: Chair Conformation of Cyclohexane. The chair conformation is the most stable form of cyclohexane due to the absence of angle and torsional strain. The absence of angle strain is a result of cyclohexane’s bond angle being very close to the ideal tetrahedral bond angle of 109.5° in its chair conformer. Similarly, the torsional strain is ...

WebThe second gauche interaction can be seen by looking from the bottom left corner: So, the 1,3-diaxial notation is the most common way we refer to the gauche interactions of axial groups in the chair conformations. Generally, the axial conformation of a given cyclohexane is less stable than the corresponding equatorial conformation. WebThe 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-cause of its resemblance to a lawn chair. If you have not already done so, you ...
