Referring to a type of organic compound that has only one carboxyl group in its structure.
Acetic acid is a common example of a monocarboxylic acid.
Monocarboxylic → It is formed from "mono-" (meaning one) and "carboxylic" (from the Greek "karbōn" meaning carbon and "oxys" meaning acid). The term refers to a type of acid that contains one carboxyl group, which is a functional group consisting of a carbon atom double-bonded to an oxygen atom and single-bonded to a hydroxyl group.
Think of 'mono-' meaning one, and 'carboxylic' referring to a type of acid with a carbon group. This helps you remember that monocarboxylic acids have just one carboxyl group.
