The acidity of a phenol is generally higher than that of an alcohol with the same number of carbon atoms. This difference in acidity can be explained by the structural differences between phenols and alcohols.Phenols are aromatic compounds that contain a hydroxyl group  -OH  directly attached to a benzene ring. Alcohols, on the other hand, have a hydroxyl group attached to an aliphatic carbon atom. The difference in acidity between phenols and alcohols is mainly due to the resonance stabilization of the phenoxide ion  the conjugate base of phenol  and the inductive effect of the aromatic ring.When a phenol loses a proton  H+  from its hydroxyl group, it forms a phenoxide ion. The negative charge on the oxygen atom in the phenoxide ion is delocalized through resonance into the benzene ring, which stabilizes the ion. This resonance stabilization makes it easier for the phenol to lose a proton and, therefore, increases its acidity.In contrast, when an alcohol loses a proton, it forms an alkoxide ion. The negative charge on the oxygen atom in the alkoxide ion is localized and not stabilized by resonance or any other significant electronic effect. As a result, alcohols are less acidic than phenols.In summary, the higher acidity of phenols compared to alcohols with the same number of carbon atoms can be attributed to the resonance stabilization of the phenoxide ion and the inductive effect of the aromatic ring, which makes it easier for phenols to lose a proton.
