Editing Chalcogen (section)

===Organic===
[[Alcohol (chemistry)|Alcohol]]s, [[phenol]]s and other similar compounds contain oxygen. However, in [[thiol]]s, [[selenol]]s and [[tellurol]]s; sulfur, selenium, and tellurium replace oxygen. Thiols are better known than selenols or tellurols. Aside from alcohols, thiols are the most stable chalcogenols and tellurols are the least stable, being unstable in heat or light. Other organic chalcogen compounds include [[thioether]]s, [[selenoether]]s and telluroethers. Some of these, such as [[dimethyl sulfide]], [[diethyl sulfide]], and [[dipropyl sulfide]] are commercially available. Selenoethers are in the form of [[side chain|R]]<sub>2</sub>Se or [[side chain|R]]SeR. Telluroethers such as [[dimethyl telluride]] are typically prepared in the same way as thioethers and selenoethers. Organic chalcogen compounds, especially organic sulfur compounds, have the tendency to smell unpleasant. Dimethyl telluride also smells unpleasant,<ref>{{cite encyclopedia |url=https://www.britannica.com/EBchecked/topic/592252/thiol |title=thiol (chemical compound)|encyclopedia = [[Encyclopædia Britannica]] |access-date=November 25, 2013}}</ref> and [[selenophenol]] is renowned for its "metaphysical stench".<ref>{{cite web|vauthors = Lowe D|url=http://pipeline.corante.com/archives/2012/05/15/things_i_wont_work_with_selenophenol.php |title=Things I Won't Work With: Selenophenol |work=In the Pipeline |date=May 15, 2012 |access-date=November 25, 2013 |archive-url=https://web.archive.org/web/20120515170845/http://pipeline.corante.com/archives/2012/05/15/things_i_wont_work_with_selenophenol.php |archive-date=May 15, 2012 |df=mdy }}</ref> There are also [[thioketone]]s, [[selenoketone]]s, and [[telluroketones]]. Out of these, thioketones are the most well-studied with 80% of chalcogenoketones papers being about them. Selenoketones make up 16% of such papers and telluroketones make up 4% of them. Thioketones have well-studied non-linear electric and photophysical properties. Selenoketones are less stable than thioketones and telluroketones are less stable than selenoketones. Telluroketones have the highest level of [[Chemical polarity|polarity]] of chalcogenoketones.<ref name="handbook"/>
