The Explanation for the Acidity of Phenols
The acidity of phenols is due to its ability to lose hydrogen ion to form phenoxide ions. ... Thus, the phenoxide ion is formed. The phenoxide ion formed is stabilized by the delocalization of negative charge due to the resonance in the benzene ring.
Hope it helps.
Answer:
The acidity of phenols is due to its ability to lose hydrogen ion to form phenoxide ions.
In a phenol molecule, the sp2hybridised carbon atom of the benzene ring attached directly to the hydroxyl group acts as an electron-withdrawing group.
This sp2 hybridized carbon atom of a benzene ring attached directly to the hydroxyl group has higher electronegativity in comparison to the hydroxyl group.
Due to the higher electronegativity of this carbon atom in comparison to the hydroxyl group attached, electron density decreases on the oxygen atom.
The decrease in electron density increases the polarity of O-H bond and results in the increase in ionization of phenols.
Thus, the phenoxide ion is formed. The phenoxide ion formed is stabilized by the delocalization of negative charge due to the resonance in the benzene ring.
Phenoxide ion has greater stability than phenols, as in the case of phenol charge separation takes place during resonance.
