hydrogen bromide and alkenes - the peroxide effect

In the next step, one of the oxygen radicals from step 1 removes a hydrogen from H–Br in another homolytic process. Here, we’re forming an H–O bond (bond dissociation energy of 102 kcal/mol for H–O in CH3OH) and breaking an H–Br bond (bond dissociation energy of 87 kcal/mol) , so a difference in … See more As discussed previously, alkenes normally react with HBr to give products of “Markovnikov” addition; the bromine ends up on the most substituted carbon of the alkene, and the … See more When the concentration of HBr and alkene become low relative to the concentration of free radical, termination can occur (See post: Initiation, … See more Note 1.

WebHydrogen bromide is the inorganic compound with the formula H Br. It is a hydrogen halide consisting of hydrogen and bromine. A colorless gas, it dissolves in water, forming hydrobromic acid, which is saturated at 68.85% HBr by weight at room temperature. WebHBr adds to alkenes to create alkyl halides. A good way to think of the reaction is that the pi bond of the alkene acts as a weak nucleophile and reacts with the electrophilic proton of HBr. Alternatively, you can view the first step of the reaction as the protonation of the pi bond. These are really just two ways to think about the same event. gernay xavierWebMECHANISM FOR REACTION OF ALKYNES WITH HBr: Step 1: A concerted termolecular reaction...
