Phenol react with bromine water
http://organicchem.org/oc2web/lab/exp/oxid/brh2o.pdf WebNitration. Phenols can undergo electrophilic substitution reactions when reacted with dilute nitric acid (HNO 3) at room temperature to give a mixture of 2-nitrophenol and 4-nitrophenol. When concentrated HNO3 is used, the product will be 2,4,6-trinitrophenol instead. A hydrogen atom in the benzene ring is substituted by a nitro (-NO 2) group.
