Prove your answer. The highest rotation axis in boat cyclohexane is the C 2 of the main mast, as it were. In fact, that's the only symmetry axis. So we'd be tempted to say that chair's C 3 goes boat's C 2 some 50% better. But wait!

The 6-vertex edge ring does not conform to the shape of a perfect hexagon. The conformation of a flat 2D planar hexagon has considerable angle strain because its bonds are not 109.5 degrees; the torsional strain would also be considerable because all of the bonds would be eclipsed bonds. Therefore, to reduce torsional strain, cyclohexane adopts a three-dimensional structure known as the chair conformation, which rapidly interconvert at room temperature via a process known as a chair … WebIf we turn it to the side we can see this is not a planar molecule.
