Title: Carboxylic Acid Formulas

What is Carboxylic Acid Formula?

  • The general molecular formula for carboxylic acid is . Carboxylic acids are nothing but organic compounds in which the carbon atom is bonded with an oxygen atom in the form of a double bond.
  • The carbon atom can also be bonded to a hydroxyl group by a single bond. There is also a fourth bond that exists and it links the carbon atom to a hydrogen atom or to some other univalent combining group. Carboxylic acid generally consists of on carboxyl group. Carboxylic acids with two or more carboxyl groups attached are called dicarboxylic acids, tricarboxylic acids, etc.
  • Carboxylic acids are a homologous series in which the compounds contain a functional group called the carboxyl group The general molecular formula for carboxylic acids is . Carboxylic acids contain at least one carboxyl group. Carboxylic acids with two or more carboxyl groups attached are called dicarborxylic acids, tricarboxylic acids, etc. Carboxylic acids are derivatives of hydrocarbons in which one or more of the hydrogen atoms in the hydrocarbon have been replaced by a carboxyl group. The first four carboxylic acids derived from alkanes are methanoic acid , ethanoic acid , propanoic acid and butanoic acid .

What is Carboxylic Acid Used For?

Answer:

Carboxylic acids and their derivatives are used in the production of polymers, biopolymers, coatings, adhesives, and pharmaceutical drugs. They also can be used as solvents, food additives, antimicrobials, and flavorings.

Why Do Carboxylic Acids Smell Bad?

Answer:

Many carboxylic acids are colorless liquids with disagreeable odors. The carboxylic acids with 5 to 10 carbon atoms all have β€œgoaty” odors. Carboxylic acids exhibit strong hydrogen bonding between molecules.
