Bromine uv radical

WebDividing one bromine molecule produces two highly reactive radicals. While UV light is needed to begin the process, further reactions do not need UV light, and so the chain … WebSep 8, 2024 · 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 can then go on to react with other species in solution (including each other) in a chain reaction.
