Why chair conformation is more stable

Jul 30, Because it minimizes so-called trans-annular interactions. Explanation: In a chair conformation, each face of the cyclohexane ring has 3 axial substituents, whose interaction is sterically unfavourable.

What is the 'true boat' conformation? This is a common and therefore important ring system, what should you know? Let's investigate in more detail some of the important features of the 3D shape of cyclohexane. The chair conformation is the most stable conformation of cyclohexane. I n chair cyclohexane there are two types of positions, axial and equatorial. The axial positions point perpendicular to the plane of the ring, whereas the equatorial positions are around the plane of the ring.

You should notice that adjacent axial postions point in opposite directions. The same is true for the equatorial positions. A second, much less stable conformer is the boat conformation. This too is almost free of angle strain, but in contrast has torsional strain associated with eclipsed bonds at the four of the C atoms that form the side of the boat.

In addition, a steric interaction of the H atoms inside the "bow" and the "stern", known as the flagpole interaction also destabilises the boat.
