# Why is benzene less saturated than cyclohexane?

Because cyclohexane, ${C}_{6} {H}_{12}$, does not contain any $\text{unsaturated bonds}$.
On the other hand, benzene, ${C}_{6} {H}_{6}$, contains $6$ delocalized $\pi - \text{electrons}$, which are contained in ring. Benzene fulfills the aromatic criterion $\left(4 n + 2 \pi \text{ electrons}\right)$, and has distinct chemistry.
