WebCarbenium ion. A carbenium ion is a positive ion with the structure RR′R″C +, that is, a chemical species with a trivalent carbon that bears a +1 formal charge . In older literature the name carbonium ion was used for this class, but now it refers exclusively to another family of carbocations, the carbonium ions, where the charged carbon is ... WebGomberg’s idea of a trivalent carbon by postulating a quinoid structure of a monomeric “triphenylmethyl” (TMP)[14] – a structural element that was of high importance for the next 15 years of vital discussions.
