Phenols are stronger acids than alcohols, but they are still quite weak acids. A typical alcohol has a pKa of 16–17. In contrast, phenol is 10 million times more acidic: its pKa is 10. Sign in to download full-size image Phenol is more acidic than cyclohexanol and acyclic alcohols beca...
Phenol is, however, more acidic than a typical alcohol such as ethanol. This can be explained by the presence of the benzene ring. The acidity of a molecule is related to the stability of the corresponding anion. When phenol loses a hydrogen ion from the hydroxy group, the corresponding phe...

to cumene hydroperoxide.When cumene hydroperoxide is treated withdilute sulfuric acid,it rearranges and splits into phenol and acetone. Because the reactants areinexpensive and the process is simple,the acidic oxidation of cumene is used to produce morethan 95% of the world’s supply of phenol...
(also referred to as phenoxide). Resonance stabilization of the phenoxide anion by the aromatic ring is one reason why phenol is more acidic than aliphatic compounds containing a -OH group. In this way, by the pi mechanism, the negative charge on oxygen is delocalized to the ortho and para...
Although phenols are often considered simply as aromatic alcohols, they do have somewhat different properties. The most obvious difference is theenhancedacidity of phenols. Phenols are not as acidic ascarboxylic acids, but they are much more acidic than aliphatic alcohols, and they are more acidic ...
