Interpretation: Phenol is found to be stronger than methanol and this difference has to be explained.
Bronsted's definition is based on the chemical reaction that occurs when both acids and bases are added with each other. In Bronsted's theory acid donates proton, while base accepts proton from acid.
When Bronsted base accepts a proton the protonated species is known as conjugate acid and when Bronsted acid loses a proton the deprotonated species is known as conjugate base.
The strength of the Bronsted acid is determined by the stability of the conjugate base that is formed from it. If there is possibility of resonance stabilization in the formed conjugate base then that will be more strong acid.
To Explain: Why phenol is more acidic than methanol.
