Hydroxyl vs. Carboxyl — What's the Difference?

The univalent group OH, a characteristic component of bases, certain acids, phenols, alcohols, carboxylic and sulfonic acids, and amphoteric compounds.

The univalent group, -COOH, the functional group characteristic of all organic acids.

(chemistry) A univalent radical or functional group (–OH) in organic chemistry; present in alcohols, phenols, carboxylic acids and certain other classes of compounds.

(organic chemistry) A univalent functional group consisting of a carbonyl and a hydroxyl functional group (-CO.OH); characteristic of carboxylic acids.

A compound radical, or unsaturated group, HO, consisting of one atom of hydrogen and one of oxygen. It is a characteristic part of the hydrates, the alcohols, the oxygen acids, etc.

The complex radical, CO.OH, regarded as the essential and characteristic constituent which all oxygen acids of carbon (as formic, acetic, benzoic acids, etc.) have in common; - called also oxatyl.

The monovalent group -OH in such compounds as bases and some acids and alcohols

The univalent radical -COOH; present in and characteristic of organic acids

Relating to or containing the carboxyl group or carboxyl radical
