=== Cyclohexane conformations ===

Certain conformations of [[cyclohexane]] and other small-ring compounds can be shown using a standard convention. For example, the standard  [[Cyclohexane conformation#Chair conformation|chair conformation]] of cyclohexane involves a perspective view from slightly above the average plane of the carbon atoms and indicates clearly which groups are [[Cyclohexane conformation#Chair conformation|axial]] (pointing vertically up or down) and which are [[Cyclohexane conformation#Chair conformation|equatorial]] (almost horizontal, slightly slanted up or down). Bonds in front may or may not be highlighted with stronger lines or wedges. The conformations progress as follows: chair to half-chair to twist-boat to boat to twist-boat to half-chair to chair. The cyclohexane conformations may also be used to show the potential energy present at each stage as shown in the diagram. The chair conformations (A) have the lowest energy, whereas the half-chair conformations (D) have the highest energy. There is a peak/local maximum at the boat conformation (C), and there are valleys/local minimums at the twist-boat conformations (B). In addition, cyclohexane conformations can be used to indicate if the molecule has any 1,3 diaxial-interactions which are steric interactions between axial substituents on the 1,3, and 5 carbons.<ref name=":02">{{Cite book |last=Brown |first=William Henry |url=https://www.worldcat.org/oclc/974377227 |title=Organic chemistry |date=2018 |others=Brent L.
