Acidity of Phenols Although phenol compounds contain an?alcohol?(-OH) group, they are?weakly acidic This is due to the?delocalisation?of one of the lone pairs from the oxygen atom into the aromatic...
Reactions of Phenol Phenols can undergo many types of reactions as both the?electron-rich benzene ring?and the?polar -OH?group can participate in chemical reactions Some of the reactions of phenols...
Production of Phenol Phenols?are organic compounds characterised by the presence of an -OH group which is attached to a benzene ring Phenols can be produced by the reaction of?phenylamine?with?nitr...
