Which reagents can be used to distinguish phenol from cyclohexanol? (Select all that apply.)

Phenol gives a violet colour with neutral $\mathrm{FeCl}{}_3$ and a white precipitate of 2,4,6-tribromophenol with bromine water; cyclohexanol does neither. Both react with sodium to evolve hydrogen, and neither reacts with Tollens reagent, so these do not distinguish them.
