Alcohols and Carboxylic acids show acidic character but their relative acidic values are different.
Basically the acidity depends upon
1. The ease of releasing the H+ ions (hydronium ions).
2. The stability of ion or molecule formed after the release of H+ ion.
now lets discuss in detail and see “why carboxylic acids are more acidic than alcohols ?”
As it is clear from the structures shown above , we can easily see the ion in case of carboxylic acid is resonance stabilised , but the ion in case of alcohol is not stable as the negative charge is confined to only one oxygen atom so it is less stable.
