Nomenclature IUPAC Bienvenue à la page de l'assistant IUPAC. Cette page et les suivantes sont destinées à vous aider dans la nomenclature des composés organiques. Le contenu de ces pages se base sur les principes essentiels de nomenclature organique repris dans l'édition 1979(1) des règles de la nomenclature IUPAC et dans le livre reprenant les recommandations de 1993(2). For those interested, an English page will be available soon. Conventions / Glossaire Vous explique entre autre l'usage de la ponctuation, des préfixes et autres parenthèses. Hydrogènes Indiqués ou Ajoutés Précise quand il est nécessaire d'indiquer les atomes d'hydrogène dans le nom. Types de nomenclature Reprend brièvement les différentes nomenclatures IUPAC en usage. Tableau des classes fonctionnelles Types de fonctions utilisés en nomenclature radico-fonctionnelle en préfixes ou en suffixes. Tableau des groupes caractéristiques Noms des groupes fonctionnels utilisés dans la nomenclature substitutive en tant que préfixes et/ou suffixes.
