Position 3 1 of 6 The difference between the nitration of arenes and phenols Reagent: arenes: concentrated nitric acid and sulfuric acid. phenol: dilute nitric acid. condition: arenes: 50-60 celius. phenols: lower temperature 2 of 6 Why can't phenol undergo esterification by heating with concentrated sulfuric acid? phenol is not nucleophilic enough because of the delocalization of electron over the ring 3 of 6 State a method to identify phenol Add orange bromine water to the phenols. Phenols can be determined when white precipitate is observed. (2,4,6-tribromophenol) 4 of 6 Condition of esterification of phenol Add acyl chloride and base(NaOH). 5 of 6 Why is the melting point of phenol relatively high? Strong hydrogen bonds. 6 of 6
