Bromonium ion

Definition

A bromonium ion is a reactive intermediate formed during the halogenation of alkenes when a bromine molecule reacts with an alkene to form a cyclic structure where the bromine atom is covalently bonded to two carbon atoms. This ion is positively charged and highly electrophilic, making it susceptible to nucleophilic attack.

Related terms

Alkene:

Unsaturated hydrocarbons containing at least one carbon-carbon double bond, acting as the substrate in halogenation reactions.

Halogenation:

A chemical reaction that involves the addition of halogen atoms (such as bromine or chlorine) to other molecules, often resulting in the formation of halogenated compounds.

Electrophilic Addition:

A type of chemical reaction where an electrophile forms bonds with nucleophiles, typically seen in the reaction mechanisms involving alkenes and alkynes
