The bromination reactions and mechanisms are compared. UV light splits the bromine molecule into two reactive radicals, resulting in a very slow loss of amber bromine color. The radical bromine atoms ...

They either undergo “bond dissociation,” where one bromine atom breaks off from the rest of the molecule, or “isomerization,” where the molecule’s atoms rearrange, but the molecule stays ...

Bromine water is an orange solution of bromine. It becomes colourless when it is shaken with an alkene. Alkenes can decolourise bromine water, but alkanes cannot. The slideshow shows this process.
