Functional class nomenclature, also called radicofunctional nomenclature, is a type of chemical nomenclature used for organic compounds.[1] It is similar in principle to the compositional nomenclature used for inorganic compounds.[2] Examples of functional class names include "methyl alcohol" and "acetic anhydride".[3]

Functional class nomenclature was once widely used for organic compounds, but it has steadily been superceded by substitutive nomenclature.[3] It remains the usual method of naming N-oxides and other N-chalcogenides, acid anhydrides, esters, and acyl halides and pseudohalides, and is often used for other functional classes such as azines, oximes, hydrazones, semicarbazones, carbohydrazones, acetals, and hemiacetals.[3]
