In organic chemistry , an electrophilic aromatic halogenation is a type of electrophilic aromatic substitution . This organic reaction is typical of aromatic compounds and a very useful method for adding substituents to an aromatic system. Image OChem Reaction HalogenationBenzene.png 400px Halogenation of Benzene where X is the halogen, catalyst represents the catalyst if needed and HX represents the protonated base. A few types of aromatic compounds, such as phenol , will react without a catalyst , but for typical benzene derivatives with less reactive substrates, a Lewis acid catalyst is required. Typical Lewis acid catalysts include AlCl sub 3 sub , FeCl sub 3 sub , FeBr sub 3 sub , and ZnCl sub 2 sub . These work by forming a highly electrophile electrophilic complex chemistry complex which attacks the benzene ring. Reaction mechanism The reaction mechanism for chlorination of benzene is the same as bromination of benzene. iron III bromide Ferric bromide and iron III chloride ferric chloride become inactivated if they react with water, including moisture in the air. Therefore, they are generated by adding iron fillings to bromine or chlorine.

He noticed that the concentration of iodine molecules oscillated and that oxygen did build up pulsating. An increase in temperature reduces the cycle in the range of hours.

During this period, most chemists rejected the phenomenon and tried to explain the oscillation by invoking heterogeneous impurities. A fundamental property of this system is that hydrogen peroxide has a redox potential which enables the simultaneous oxidation of iodine to iodate 5 H sub 2 sub O sub 2 sub I sub 2 sub 2 IO sub 3 sub sup sup 2 H sup sup 4 H sub 2 sub O and the Redox reduction of iodate back to iodine 5 H sub 2 sub O sub 2 sub 2 IO sub 3 sub sup sup 2 H sup sup I sub 2 sub 5 O sub 2 sub 6 H sub 2 sub O Between these two reactions the system oscillates causing a concentration jump of the iodide and the oxygen production.
