A halonium ion is any onium ion containing a halogen atom carrying a positive charge. They correctly argued that if the initial reaction intermediate in bromination is the open-chain X–C–C+, rotation around the C–C single bond would be possible leading to a mixture of equal amounts of dihalogen syn isomer and anti isomer, which is not the case. In 1970 George A. Olah succeeded in preparing and isolating halonium salts by adding a methyl halide such as methyl bromide or methyl chloride in sulfur dioxide at −78 °C to a complex of antimony pentafluoride and tetrafluoromethane in sulfur dioxide.

A halonium ion in organic chemistry is any onium compound (ion) .

A halonium ion in organic chemistry is any onium compound (ion) containing a halogen atom carrying a positive charge. These ions are usually only short-lived reaction intermediates; they are very reactive, owing to high ring strain in the three-membered ring and the positive charge on the halogen; this positive charge makes them great electrophiles.

Get adequate with reactive intermediates,carbocations, carbanions, free radicals . Reference books of Organic Chemistry. Complete JEE Main/Advanced Course and Test Series.

Get adequate with reactive intermediates,carbocations, carbanions, free radicals, carbenes, arenium ions and benzynes with the help of study material for IIT JEE and other exams by askIITians. These reactive intermediates are not isolated, but are detected by spectroscopic methods, or trapped chemically or their presence is confirmed by indirect evidence. Carbocations are the key intermediates in several reactions and particularly in nucleophilic substitution reactions.

As these intermediates are highly reactive, they cannot usually be isolated, but their existence and structure can be proved by theoretical and experimental methods. Books related to Reactive Intermediates in Organic Chemistry. The chapters are clearly structured and are arranged according to the type of intermediate, providing information on the formation, characterization, stereochemistry, stability, and reactivity of the intermediates.
