WebJan 28, 2024 · The bromine atom in the bromonium ion acts as a shield in a way, forcing the bromonium anion to attack from the opposite side as it. The result of this is the ring opening up with the two halogens on opposite sides as each other. This is anti stereochemistry, which is defined as the two bromine atoms come from opposite faces of the double bond. WebFigure 10.4e Formation of Halohydrin Figure 10.4f Mechanism: reaction of bromine water with cyclohexene In the second step of the mechanism, both H 2 O (solvent) and Br – (produced in the first step) are nucleophiles and have the chance to react with the cyclic bromonium ion.

WebAlso this reaction is used as a qualitative test for the presence of an alkene (Baeyer's Test ). This decolorization of bromine water is often used as a test for a carbon-carbon double bond. The addition of bromine to cyclohexene gives a racemic trans product. Since the product is colorless, the bromine is rapidly decolorized when added to an ... WebR-H + Br2 → R-Br + HBr. UV light splits the bromine molecule into two reactive radicals, resulting in a very slow loss of amber bromine color. The radical bromine atoms can then …
