Carbenium ion

A carbenium ion is a carbocation of the trivalent and classical type R3C+. A carbonium ion is a carbocation of the penta- or tetracoordinated nonclassical type such as an ion of the type R5C+. Carbonium ions appear as nonclassical carbocations such as the norbornyl cation These definitions have been proposed by the chemist George Andrew Olah in 1972 [1] and now widely accepted. In older literature a carbocation of the type R3C+ may still be referred to as a carbonium ion.
