The boat conformations spontaneously distorts to twist-boat conformations. Here the symmetry is D 2, a purely rotational point group with three twofold axes. This conformation can be derived from the boat conformation by applying a slight twist to the molecule so as to remove eclipsing of two pairs of methylene … See more 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, … See more The different conformations are called "conformers", a blend of the words "conformation" and "isomer".

The situation becomes more complex with substituted … See more Heterocyclic analogs of cyclohexane are pervasive in sugars, piperidines, dioxanes, etc. They exist generally follow the trends seen for cyclohexane, i.e. the chair conformer being most stable. The axial–equatorial equilibria (A values) are however strongly … See more Another way to compare the stability within two molecules of cyclohexane in the same conformation is to evaluate the number of coplanar carbons in each molecule. Coplanar carbons are carbons that are all on the same plane. Increasing the number of coplanar carbons … See more Chair to chair The interconversion of chair conformers is called ring flipping or chair-flipping. Carbon–hydrogen … See more Conformational equilibrium is the tendency to favor the conformation where cyclohexane is the most stable. This equilibrium depends on the interactions between the … See more

Webthis reaction proceeds through a transition state with a chair conformation. However, the transformation of schkuhriolide (germa-crane) into elemanschkuhriolide (elemane) may occur through a boat transition state due to the final configuration of the eleman-schkuhriolide, but this transition state is questionable due to its high energy.
