WebTranscript Halogenation 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

Explaining electrophilic addition involving hydrogen halides

WebJan 28, 2024 · Mechanism Step 1) Electrophilic Attack During the first step of the mechanism, the 2 pi electrons from the double bond attack the H in the HBr electrophile which is shown by a curved arrow. The two pi electrons form a C-H sigma bond between the hydrogen from HBr and a carbon from the double bond. WebBromine is more electronegative than hydrogen. That means that the bonding pair of electrons is pulled towards the bromine end of the bond, and so the hydrogen bromide … examples of simple mechanisms

Ethene + HBr Reaction CH2=CH2 + HBr Mechanism

WebThe reaction with bromine happens at room temperature. If you have a gaseous alkene like ethene, you can bubble it through either pure liquid bromine or a solution of bromine in an organic solvent like tetrachloromethane. The reddish-brown bromine is decolourised as it reacts with the alkene. WebAdditional information. This is a resource from the Practical Chemistry project, developed by the Nuffield Foundation and the Royal Society of Chemistry.This collection of over 200 practical activities demonstrates a … WebThis page gives you the facts and a simple, uncluttered mechanism for the electrophilic addition reactions between bromine (and the other halogens) and alkenes like … examples of simple molecular crystals
