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.

WebBy twisting the boat conformation, the steric hindrance can be partially relieved, but the twist-boat conformer still retains some of the strains that characterize the boat conformer. Finally, by lifting one carbon above the ring plane and the other below the plane, a relatively strain-free chair conformer is formed. WebSep 1, 2009 · The multifrequency and pulsed EPR measurements clarified that the inhomogeneously broadening spectra were ascribable to the distribution of the dihedral …
WebShort answer: yes, the dioxane has a minimum when it's in a twist-boat form. I use Avogadro which offers a "auto-optimize" tool. You can grab atoms and throw them around to force rings into different conformations while the force field is minimizing. So here's what I did.
