Why are carboxylic acids more acidic than alcohols or phenols although all of them have hydrogen atom attached to a oxygen atom (-O-H)?

Explanation

Carboxylic acids are more acidic than alcohol or phenol, although all of them have O-H bond. This can be explained on the basis of stability of conjugate base obtained after removal of `H^(+)` from acid or phenol.

Hence, dissociation of O-H bond in case of carboxylic acid become easier than that of phenol. Hence, carboxylic acid are stronger acid than phenol.
