Cyclohexane gauche
Did you know?
Gauche interactions occur when a non-hydrogen substituent on a cyclohexane occupies the equatorial position. The equatorial substituent is in a staggered position with the 2-carbons relative to itself (there will be two such carbons and thus two 1,2 gauche interactions). 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". Chair conformation The chair conformation is the most stable conformer. At 298 K (25 °C), 99.99% of all molecules in a … See more Conformational equilibrium is the tendency to favor the conformation where cyclohexane is the most stable. This equilibrium … 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 … See more Chair to chair The interconversion of chair conformers is called ring flipping or chair-flipping. Carbon–hydrogen … See more In cyclohexane, the two chair conformations have the same energy. The situation becomes more complex with substituted derivatives.

Webconformation, a “gauche butane” interaction is found between the substituent on one carbon and a non-hydrogen atom on an adjacent carbon. There are two gauche butane interactions in axial methyl-cyclohexane. Each gauche butane contributes 0.9 kcal/mol of instability meaning the axial methyl is roughly 1.8
