Web16 jul. 2016 · Carbocations form by one of two basic mechanisms: Heterolytic bond cleavage by the loss of a leaving group. Addition of π electrons to an electrophile. A carbocation is an organic molecule, an intermediate, that forms as a result of the loss of two valence electrons, normally shared electrons, from a carbon atom that already has … WebMetals are capable of forming ions by losing electrons, and this is true of aluminum which can lose three electrons. If the result of a change in charge produces a positive ion, the ion is referred to as a cation. Cations are denoted by the element that comprises them, so in this instance, there is an aluminum cation.
