It exists as a 50:50 mixture of enantiomeric conformations, which interconvert so rapidly they cannot be resolved (ie. separated). Since the cis isomer has two centers of chirality (asymmetric carbons) and is optically inactive, it is a meso-compound. rocky mountain sparkling water

WebCyclohexane has an angle of 120°, and you would think that it would have angle strains. However, cyclohexane has a form of chair conformation. Although the bond angle is 120° in the plane, cyclohexane has a bond angle of 109.5° when considered in terms of stereochemistry.

"WebWhich has the higher symmetry: chair or boat? 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! " - Point group of chair cyclohexane

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.
