dbo:abstract |
Le cation méthylium est l'espèce chimique de formule CH3+. C'est un carbocation de type carbénium, avec un atome de carbone en configuration plane trigonale due à une hybridation sp2. Il est bien connu pour sa réaction de recombinaison dissociative dans le milieu interstellaire ou dans l'ionosphère de certaines planètes : CH3+ + e− → :CH2 + H·. (fr) In organic chemistry, methenium (also called methylium, carbenium, methyl cation, or protonated methylene) is a cation with the formula CH+3. It can be viewed as a methylene radical (:CH2) with an added proton (H+), or as a methyl radical (•CH3) with one electron removed. It is a carbocation and an enium ion, making it the simplest of the carbenium ions. (en) |
