Generally, however, carboxylic acids are not as chemically active as the non-organic mineral acids such as hydrochloric acid or sulfuric acid. although carboxylic acid has the ability to form hydrogen bonding, however carboxylic anion will exist as an ionic salt, and ionic salts are highly stable due to partial charge on oxygen and hydrogen of water. They are much more acidic that H2O (pKa 15. 05, and 4-chlorobutanoic acid has pKa = 4. Increase in the distance of Halogen from COOH decreases the acidity e. Carboxylic Acids are named according to the same system as other organic compounds, with the suffix -oic acid used to indicate that both a carbonyl group and a hydroxyl group are both attached to the same carbon atom, which is located at the end of a chain or branch of carbon atoms forming the molecule (except in the case of methanoic acid, which includes only one carbon atom). Carboxylic acids are an important class of organic compounds. An ester is an organic compound where the hydrogen in the carboxyl group is replaced with a hydrocarbon chain.
