Reaction of alkene with br2
WebOverview of Reaction of Alkanes with Br₂ Alkanes are the most basic of all organic compounds and undergo very few reactions. The two important reactions involve combustion and halogenation, i.e., the substitution of a single hydrogen element on the alkane for a single halogen that forms a haloalkane. WebAlkenes react in the cold with pure liquid bromine, or with a solution of bromine in an organic solvent like tetrachloromethane. The double bond breaks, and a bromine atom becomes attached to each carbon. The bromine loses its original red-brown colour to give a …
