Chair Conformation Of Cyclohexane Is Most Stable

The chair form is stable.
Chair conformation of cyclohexane is most stable. A second much less stable conformer is the boat conformation. The boat form is metastable. All carbon centers are equivalent.
What this means is that in going from chair to boat the molecule has to undergo an increase in ring strain which is mostly relieved once the straightened portion is able to relax into the end of the boat conformation. The new conformation puts the carbons at an angle of 109 5. Six hydrogen centers are poised in axial positions roughly parallel with the c 3 axis.
Get your answers by asking now. It is well known that the chair conformation of cyclohexane is the most stable of its conformers. At 25 c 99 99 of all molecules in a cyclohexane solution adopt this conformation.
Between a and c the choice is clear. The chair conformation is the most stable conformation of cyclohexane. The first step in drawing the most stable conformation of cyclohexane is to determine based on whether the substituents are cis or trans to one another and based on where they re located on the ring what the choices of axial and equatorial positions are for the substituents.
Looking at the bond line diagram. The idea that the chair conformation is the most stable structure for cyclohexane was first proposed as early as 1890 by hermann sachse but only gained widespread acceptance much later. Chair conformation of cyclohexane is more stable than boat form because in chair conformaion the c h bonds are equally axial and equatorial i e out of twelve c h bonds six are axial and six are equatorial and each carbon has one axial and one equatorial c h bond.
The symmetry is d 3d. 1 the most stable conformation of cyclohexane is the chair conformation. A is more stable since the larger group is in the equatorial position.
