In organic chemistry, methenium (also called methylium, carbenium,[2] methyl cation, or protonated methylene) is a cation with the formula CH+
3
. It can be viewed as a methylene radical (:CH
2
) with an added proton (H+
), or as a methyl radical (•CH
3
) with one electron removed. It is a carbocation and an enium ion, making it the simplest of the carbenium ions.[3]
