What is Phenol? Medical Uses, Health Benefits, and Risks
WebNow the negative charge on the conjugate base can be spread out over two oxygens (in addition to three aromatic carbons). The phenol acid therefore has a pK a similar to that of a carboxylic acid, where the negative charge on the conjugate base is also delocalized to two oxygen atoms. The ketone group is acting as an electron withdrawing group – it is ‘pulling’ … WebPhenol is a weak acid. In aqueous solution in the pH range ca. 8 - 12 it is in equilibrium with the phenolate anion C6H5O− (also called phenoxide or carbolate ): [9] Resonance structures of the phenoxide anion Phenol is more acidic than aliphatic alcohols. The differing pKa is attributed to resonance stabilization of the phenoxide anion.
