The ring delocalisation is permanently broken and a chlorine or bromine atom adds on to each carbon atom. You get the dibromo alkane.          | halides. They react rapidly with bromine, for example, to add a Br 2 molecule across the C=C double bond. Under UV light, $\ce{Br2}$ undergoes homolytic splitting to generate $\ce{Br*}$ radicals: The formation of 3-bromocyclohexene is an example of substitution of alkanes, which require the free-radical mechanism: In the first step of the upper mechanism, which is also the rate-determining step, a stable allyl radical is generated, which is stabilized by resonance: As a result, the activation energy of the first step is significantly lowered. MathJax reference. Both products are formed although 3-bromocyclohexene is the major product. The reaction between hexene and bromine in presence of light gives 3-bromocyclohexene. molecule across the C=C double bond. I'm creating an App, which country's law will be applied to it? 1.
