Keten
[edit]Hi folks, in the article is stated that ketenes belong to the cumulenes. The Gold Book [1] denies that:
- Cumulenes in which one or more carbon atoms of the cumulative bond system have been replaced by heteroatoms. E.g. O=C=C=C=O, but not CH2=C=O, ketene, nor O=C=O, carbon dioxide, which are heteroallenes.
Please check and correct if necessary. Thanks --Mabschaaf (talk) 21:46, 17 January 2011 (UTC)

Thinnest thing possible?
[edit]Is this the thinnest thing that can possibly exist? It seems like a likely candidate. — Preceding unsigned comment added by 134.134.137.78 (talk) 21:28, 28 June 2025 (UTC)
