Cis and trans chair conformations
WebConformations of Cyclohexane. A planar structure for cyclohexane is clearly improbable. The bond angles would necessarily be 120º, 10.5º larger than the ideal tetrahedral angle. Also, every carbon-carbon bond in such a structure would be eclipsed. The resulting angle and eclipsing strains would severely destabilize this structure. WebA.

WebCyclohexane contains a six-membered saturated cyclic ring that experiences severe angular strain in the corresponding planar form. Hence, cyclohexane exists in chair conformations where the angular strain becomes nil. There are two available positions for the substituents in the chair conformation, i.e., equatorial and axial. WebAssuming you have practiced drawing chairs, this is what you need to do to draw the ring-flip of any substituted cyclohexane: Step 1. Number the atoms in the ring (the starting point and the direction doesn’t matter). In this case, we will go clockwise: Step 2. Label wedge groups as pointing Up and dash lines as pointing Down.
