Eetterien
Could you clarify what you mean by "eetterien"? The term does not correspond to a widely recognized concept in standard chemical nomenclature. Do you mean:
- ethers (the organic compounds with the R–O–R' linkage), perhaps in a particular language variant?
- a term from another language (for example Dutch or German usage) that translates differently in English?
- a fictional or specialized concept not commonly used in general chemistry?
With a bit more context or a source, I can draft a concise, neutral wiki-style article under
