mini|alternativtext=Strukturformel von 2,2,3,3,4,4,-Hexamethylpentan, einem Isomer von Undecan|Strukturformel von 2,2,3,3,4,4,-Hexamethylpentan, einem Isomer von Undecan Die Undecane bilden eine Stoffgruppe aus der Gruppe der Alkane. Namensgeber ist der lineare Vertreter Undecan. Die Undecane umfassen theoretisch 159 konstitutionsisomere bzw. 345 konstitutions- und konfigurationsisomere Verbindungen mit der Summenformel C11H24. In öffentlich verfügbaren Datenbanken werden (Stand März 2024) zwischen 62 und 177 tatsächlich bekannte Isomere geführt.

Verwendung Die Isomere des Undecans finden in der Trennung von Alkylphenolen mittels Azeotroprektifikation Verwendung, bei der die Isomere als Schleppmittel benutzt werden.

Konstitutionsisomere Die folgende Tabelle gibt einen Überblick über alle theoretisch möglichen konstitutionsisomeren Undecane, gruppiert nach Anzahl der Kohlenstoffatome in der Hauptkette bzw. nach den Substituenten:
