Why Phenol Is A Weak Acid?

Phenol is stable with benzene ring as it has a conjugation of lone pair of oxygen. Phenol becomes prone to donate proton when there is a development of positive charge on the oxygen atom as the polarity of OH bond increases. When phenol donates a proton, it becomes a conjugate base as there is a formation of phenoxide ion. Therefore, the donation of proton makes phenol becomes stable making it a weak acid.
