A cyclohexane molecule is six-different tetrahedral carbons linked together in a circle—hence, cyclohexane.
- When viewed from the top it looks like a hexagon.
- When viewed from the side, the carbon atoms are puckered, because the angles are 109.5°. Organic chemists call this sideway view of cyclohexane a chair.
- Cyclohexane is always moving back and forth between its two possible chair orientations, these are called conformational isomers.
- This movement is called a ring flip.
- As the chairs flip, so do the bonds attached to the carbons.
