Alkene chlorination
WebAlkenes, as a functional group, is a very versatile one. You can reduce it, you can oxidize it, you can cleave it, and you can do a large number of various addition reactions modifying … WebThis is due to the abstraction of a hydrogen atom by the alkene from the acid (HX) to form the most stable carbocation (relative stability: 3°>2°>1° >methyl), as well as generating a halogen anion . A simple example of a hydrochlorination is that of indene with hydrogen chloride gas (no solvent): [4]

WebTHE HALOGENATION OF ALKENES. This page looks at the reaction of the carbon-carbon double bond in alkenes such as ethene with halogens such as chlorine, bromine and iodine. This is called halogenation. Reactions where the chlorine or bromine are in solution (for example, "bromine water") are slightly more complicated and are treated separately ...
