WebThe 1,4-dibromide is only formed when the reaction is heated and is the thermodynamic product. The mechanism is the electrophilic attack on the diene to give a bromonium ion, which bromide opens to give the dibromide. 1,2-dibromide can then react further because it can undergo nucleophilic substitution. Bromide is a good nucleophile and leaving ... WebThe reaction between bromine and alkenes is an example of a type of reaction called an addition reaction. The bromine is decolourised because a colourless dibromo compound forms. For example:...

WebThe electrophilic addition of bromine to propene The attraction between the propene and the bromine The double bond in all alkenes is made up of two different parts. One pair of electrons lies on the line between the two nuclei where you would expect them to be. This is called a sigma bond. WebThe mechanisms. The reactions are examples of electrophilic addition. With ethene and HBr: and with cyclohexene: Electrophilic addition reactions involving the other hydrogen halides. The facts. Hydrogen chloride and the other hydrogen halides add on in exactly the same way. For example, hydrogen chloride adds to ethene to make chloroethane: WebHalogenation is a reaction that occurs when one or more halogens are added to a substance. Halogens comprise the seventh column in the periodic table and include fluorine, chlorine, bromine, iodine, and astatine. The resulting product of a halogenation reaction is known as a halogenated compound. Created by Jay. Sort by: Top Voted Questions loft gaithersburg md
