Which reagents can be used to distinguish phenol from cyclohexanol?

Neutral $\mathrm{FeCl}{}_3$ gives a violet colour only with phenol, bromine water gives a white precipitate only with phenol, and an alkaline diazonium salt couples with phenoxide to give an orange-red azo dye but not with cyclohexanol. Sodium metal liberates $\mathrm{H}{}_2$ from both compounds, so it cannot distinguish them.
