1. Carbocation

   A carbocation is an ion with a positively charged carbon atom. Among the simplest examples are the methenium CH+3, methanium CH+5 and vinyl C2H+3 cations. Occasionally, carbocations that bear more than one positively charged carbon atom are also encountered (e.g., ethylene dication C2H2+4).Until the early 1970s, all carbocations were called carbonium ions. In the present-day definition given by the IUPAC, a carbocation is any even-electron cation with significant partial positive charge on a carbon atom. They are further classified in two main categories according to the coordination number of the charged carbon: three in the carbenium ions and five in the carbonium ions. This nomenclature was proposed by G. A. Olah. Carbonium ions, as originally defined by Olah, are characterized by a three-center two-electron delocalized bonding scheme and are essentially synonymous with so-called 'non-classical carbocations', which are carbocations that contain bridging C–C or C–H σ-bonds. However, others have more narrowly defined the term 'carbonium ion' as formally protonated or alkylated alkanes (CR+5, where R is H or alkyl), to the exclusion of non-classical carbocations like the 2-norbornyl cation.

1. Carbocation

   A carbocation is an ion with a positively-charged carbon atom. Among the simplest examples are methenium CH+ 3, methanium CH+ 5, and ethanium C2H+ 7. Some carbocations may have two or more positive charges, on the same carbon atom or on different atoms; such as ethylene dication C2H2+ 4. Until the early 1970s, all carbocations were called carbonium ions. In present day chemistry a carbocation is any positively charged carbon atom, and they are classified in two main categories according to the valence of the charged carbon: three in the carbenium ions, and five or six in the carbonium ions. This nomenclature was proposed by G. A. Olah.
