How does the structure of benzene differ from the cyclohexane structure?

Cyclohexane does not have an aromatic circle.

Explanation:

Hi,
Cyclohexane has no double bonds between the carbons, its formula is C6H12, while benzene has 3 double bonds with the formula C6H6. Those double bonds are conjugated with the rest of the molecule, which is what we call an "aromatic" cycle.

Well, for a start, the aromatic benzene ring is PLANAR...

Explanation:

Well, for a start, the aromatic benzene ring is PLANAR...i.e. a six-membered ring with all the carbon and hydrogen nuclei occupying the same plane, and each $\angle C - C - C$ and $\angle C - C - H = {120}^{\circ}$. On the other hand, the ${C}_{6} {H}_{12}$ is somewhat puckered...and you should address models to appreciate the axial and equatorial substituents with respect to each ring carbon...
