Abstract:
Although the addition of halogens at the double bond is one of the most general reactions of unsaturated compounds, there is extreme variation of reactivity displayed by different unsaturated compounds towards halogens. Considerable complexity is revealed by Kinetic investigations, and the celerity of halogen addition to certain olefins (e.g. ethylene and styrene) is deceptive if taken to signify that the reaction mechanism is simple. As well as the internal structure of the compound itself, there are considerable effects produced in certain reactions due to the external factors temperature, light, solvent, and catalysts.
