Comparison of acidity of alcohols and carboxylic acids.

No comments

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.
