# Reaction between free radicals and water

Free-radical substitution does not occur in aqueous solution as free radicals react with water (from school textbook). What does the reaction between free radicals, say Br, and water produce?

• You might be referring to electrophilic addition like in the video - I am referring to radical substitution. In your first link there is such a reaction but with Cl radicals instead. Was wondering what happens when these radicals react with water. – Kenneth Sep 4 '16 at 12:31
• You're right. I deleted my unhelpful comments. – DHMO Sep 4 '16 at 12:41
• My best guess would be HBr. Br2 + Water disproportions to HBr and hypobromite. That reaction is sped up by light, so it's probably a radical reaction. – Karl Sep 4 '16 at 12:51

$$\ce{Br* + H2O -> HBr + *OH}$$
$$\ce{*OH + Br2 -> BrOH + Br*}$$
