Radicofunctional names are advantageous for naming substituted ethers. According to the latest recommendations of IUPAC different systems of nomenclature can be used even for naming one class of compounds. For example, for naming unsymmetrical ethers with several oxygen atoms, replacement nomenclature is recommended. The system of nomenclature to be chosen depends on the ease with which it can be used to name a given compound. As it is a substituted symmetrical ether, it is named as bis(2-methoxyethyl)ether.
