Study Notes

Carboxylic Acids

The functional group present in carboxylic acid is -COOH, where the carbon atom is bonded to an oxygen atom and a hydroxyl (-OH) group.

Structure and Formula

The general formula for carboxylic acids is R-COOH, where R is a hydrocarbon chain.
The structure of a carboxylic acid molecule consists of a hydrocarbon chain (R) attached to a carboxyl (-COOH) group.

Examples

Formic acid (HCOOH) is an example of a carboxylic acid.

Acidity

Carboxylic acids are acidic, with the acidity increasing as the size of the hydrocarbon chain (R) decreases.

Uses

Carboxylic acids are used in the production of soaps, detergents, and plastics.
They are also used as preservatives and flavorings in the food industry.
Carboxylic acids are used in the pharmaceutical industry for the production of certain medications.
