A cyclohexane conformation is any of several three-dimensional shapes adopted by a cyclohexane molecule. Only one C – C bond rotates to attain the next conformation, or two C-atoms move as shown by the arrows, to attain the next conformer. This deviation in bond angle from the ideal bond angle 109.5° would bring some kind of ring strain into the structure. In the chair form of cyclohexane, the carbon atoms and the bonds around them are almost perfectly tetrahedral. How can I draw boat cyclohexanes step-by-step? So the C-C-H angles will be almost exactly 109.5 degrees. Because many compounds feature structurally similar six-membered rings, the structure and dynamics of cyclohexane are important prototypes of a wide range of compounds. If cyclohexane has a planar structure, then the bond angles would be 120°. The molecular formula of cyclohexane is C6H12. Each #"C-C-C"# bond angle in a planar cyclohexane would be 120 °. (Note that while you defined the bond midpoint, the angle will be the same regardless of whether it's the midpoint of the bond or the neighboring carbon atom itself.)
