CARBOXYLIC ACID

Carboxylic acid is an organic compound containing a carboxyl functional group attached to an R-group, referring to an alkyl group or maybe aryl. The general formula of this acid is R-COOH. It may be classified as, mono, di, tricarboxylic acid. Examples are:

Formic acid, H-COOH, Crotonic acid, CH3CH=CH-COOH, Butyric acid, CH3(CH2)2COOH.

Carboxylic acid is said to be a weak acid. A large carboxylic acid with three ionizable hydrogen atoms is termed citric acid. It is present in citrus fruits and provides them with a sour taste. Carboxylic acid molecules are polar; they take part in hydrogen bonding. These compounds, if placed in nonpolar solvents, form dimers via hydrogen bonding. The solubility of compounds containing the carboxyl functional group depends on the size of the compound. The smaller the compound, the higher the solubility for water. They are soluble in organic solvents. As their mass increases, solubility decreases. These compounds are Bronsted-Lowry acids as having the ability to donate protons. They commonly have a strong pungent smell. However, their esters have pleasant odors. Although Carboxylic acid is a week acid, it is more acidic than alcohol. Its structure is associated with dimeric structures and intermolecular interactions with each other.

Carboxylic acids have extensive applications.

• They are used in the production of food additives and other solvents.
• They can be used as flavoring and antimicrobials.
• They are used in the production of coating, polymers, and biopolymers.
• They serve in the production of adhesives and pharmaceutical drugs.
• They are utilized in the synthesis of acetone and Easters.
• They work as mordant and helps in the silvering of mirror.
• They serve as insect repellent for flies or mosquitoes.
• They assist in the treatment of acne and dandruff.
