Which chair structure is the most stable?

cyclohexane
The most stable conformation of cyclohexane is the chair form shown to the right. The C-C-C bonds are very close to 109.5o, so it is almost free of angle strain. It is also a fully staggered conformation and so is free of torsional strain.

Which chair flip is more stable?

The chair conformation is the most stable conformation of cyclohexane. A second, much less stable conformer is the boat conformation.

Which conformation is more stable boat or chair?

The chair conformation is more stable than the boat conformation. The boat conformation can sometimes be more stable than it is usually, by a slight rotation in the C-C bonds and is called the skew boat conformation. Nevertheless, the chair conformation is the most stable cyclohexane form.

Which conformation is more stable?

staggered conformation
hydrocarbons. …with respect to the other—the eclipsed conformation is the least stable, and the staggered conformation is the most stable. The eclipsed conformation is said to suffer torsional strain because of repulsive forces between electron pairs in the C―H bonds of adjacent carbons.

How to choose the more stable chair conformation?

For example, the energy difference of the axial and equatorial isopropyl cyclohexane is 9.2 kJ/mol. So, choosing the more stable chair conformation is straightforward when there is only one group on the cyclohexane. You just need to find the energy value for the axial group:

How to calculate the stability of a chair?

Draw both chair conformation (ring-flip) and use the table to calculate the relative energy cost associated with each group in the axial position to determine the more stable chair conformation of each of the following compounds: This content is for registered users only. Click here to Register!

Which is more stable axial or equatorial chair?

For example, the energy difference of the axial and equatorial isopropyl cyclohexane is 9.2 kJ/mol. So, choosing the more stable chair conformation is straightforward when there is only one group on the cyclohexane.

Which is more stable, a 3 legged chair or a 4 legged chair?

Four supporting points do not possess this property. Therefore, even if all three legs are of different lengths, they still touch the supporting surface. When speaking about four legs, one leg will “hang” in the air. This gives the impression that 4-legged-chair is less stable.
