IUPAC nomenclature uses substitutive naming by replacing "e" with functional group suffixes. Principle functional group is determined by comparing relative positions in priority table. Groups can act as principle functional groups or side chains
Organic compounds contain carbon-hydrogen or carbon-carbon bonds. Nomenclature is the systematic naming of organic compounds. IUPAC was founded in 1919 to standardize organic compound naming
Heteroatoms are atoms other than carbon and hydrogen in organic compounds. Common heteroatoms include oxygen, nitrogen, sulfur, and halogens. Heteroatoms can be common (like O in water) or rare (like P in organophosphates)
IUPAC nomenclature is recommended by International Union of Pure and Applied Chemistry. Every organic compound should have unambiguous structural formula. Official names are not always followed in practice. Common names are often shorter and clearer than systematic ones
Organic chemistry studies carbon-containing compounds and their properties. Organic compounds form basis of all earthly life and most known chemicals. Study includes structure, properties, reactions, and synthesis
Organic chemistry studies carbon compounds with unparalleled chemical diversity. Carbon atoms form strong bonds with other carbon and elements. Carbon is not abundant but found in all living things. Carbon compounds containing carbonate ions are excluded from organic chemistry
