WebAlkanes: Bromination (substitution reaction) R-H + Br2 → R-Br + HBr ( colorless) (amber) (colorless) 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. WebAs illustrated by the preceding general equation, strong Brønsted acids such as HCl, HBr, HI & H 2 SO 4, rapidly add to the C=C functional group of alkenes to give products in which new covalent bonds are formed to hydrogen and to the conjugate base of the acid. WebTreatment with an alkene gives an anti-Markovnikov addition of H and OH across the alkene. The reaction proceeds exclusively via a syn addition. 1) BH3*THF (name of Reaction) 2) H2O2, NaOH Hydroboration- oxidation Hydroboration- oxidation (image) Sets found in the same folder Organic Chemistry - Alkene reactions 15 terms cgalv022 hange wallpaper aot
