• International Union of Pure and Applied ChemistryBroader topic: IUPAC develops the naming rules used to identify chemical compounds consistently.

• KetoneRelated: Ketone names commonly use the suffix -one and specify the carbonyl position.

• AlkyneRelated: Its rules specify how to name and number alkyne chains and substituents.

• Chemical nomenclatureBroader topic: Its recommendations provide the principal framework for systematic chemical names.

• Alkyl groupRelated: IUPAC names identify alkyl substituents by carbon count and position.

• EtheneRelated: The suffix “-ene” in ethene identifies its carbon–carbon double bond.

• EpoxideRelated: Systematic names distinguish epoxide structures and specify their positions and substituents.

• Systematic element nameRelated: The provisional element-name rules are part of IUPAC's broader naming standards.

• Quaternary ammonium compoundRelated: Systematic naming distinguishes the four nitrogen substituents and identifies the associated counterion.

• R–S notationRelated: R–S descriptors specify stereochemistry within systematic names of compounds.

• Ethyl groupRelated: It specifies how an ethyl substituent is named and positioned in compound names.

• HexaneRelated: Its rules distinguish hexane's branched isomers from the straight-chain compound.

• Homologous seriesRelated: Systematic names distinguish successive members while preserving their shared structural pattern.

• Absolute configurationRelated: Systematic names can include R/S descriptors to distinguish stereoisomers.

• Amino groupRelated: It distinguishes amino substituents from amines treated as the principal functional group.

• Maleic acidRelated: The systematic name (Z)-but-2-enedioic acid encodes maleic acid’s structure and configuration.

• Acyl groupRelated: Its rules distinguish acyl substituent names such as acetyl and benzoyl.

• Caproic acidRelated: The systematic name hexanoic acid encodes its six-carbon chain and acid group.

• EthanolamineRelated: The systematic name 2-aminoethan-1-ol specifies the positions of both groups.

• PhenethylamineRelated: The systematic name, 2-phenylethan-1-amine, encodes the scaffold’s chain and functional group.

• Structural isomerRelated: Systematic names distinguish compounds with the same formula but different structures.

• DodecaneRelated: The name combines the twelve-carbon root “dodec-” with the alkane ending “-ane.”

• AdamantaneRelated: Adamantane’s name is retained as the parent for many substituted cage derivatives.

• Butyl acetateRelated: Systematic names distinguish butyl acetate’s chain and branching isomers.

• Glutaric acidRelated: Its systematic IUPAC name, pentanedioic acid, describes the chain and terminal acid groups.

• HaloalkaneRelated: Haloalkane names identify halogen substituents and their positions on the carbon chain.

• Parent hydrideNarrower topic: Parent hydrides are one structural basis for names in this system.

• SubstituentRelated: IUPAC names identify substituents and specify their positions on a parent structure.

• 1-PropanolRelated: The name 1-propanol identifies a three-carbon chain and locates the hydroxyl group at carbon 1.

• Allyl chlorideRelated: The systematic name, 3-chloroprop-1-ene, identifies the compound’s structure.

• ButanoneRelated: The name butanone identifies a four-carbon chain with a ketone group.

• PentadecaneRelated: The name encodes a fifteen-carbon parent chain and the alkane ending.
