Carboxylic acids tend to release h+ ions more easily than alcohol. which of the following is the correct explanation for their increased acidity?

Regretfully, you have not included in the question, the choices that would be our guide to arriving in the answer to this query. However, as a general knowledge, the acidity of a substance can be measured by its pH which is equal to,
                          pH = -log[H+]
which means that the increase in H+ ions will lead to the decrease in pH. A smaller pH value denotes that the substance is more acidic. 

The answer will be d
