HBr + CH 2 Cl 2 → HCl + CH 2 BrCl HBr + CH 2 BrCl → HCl + CH 2 Br 2. These metathesis reactions illustrate the consumption of the stronger acid (HBr) and release of the weaker acid (HCl). Allyl bromide is prepared by treating allyl alcohol with HBr: CH 2 =CHCH 2 OH + HBr → CH 2 =CHCH 2 Br + H 2 O. HBr adds to alkynes to yield bromoalkenes.

Hydrobromic acid is an aqueous solution of hydrogen bromide.It is a strong acid formed by dissolving the diatomic molecule hydrogen bromide (HBr) in water. "Constant boiling" hydrobromic acid is an aqueous solution that distills at 124.3 °C (255.7 °F) and contains 47.6% HBr by mass, which is 8.77 mol/L. Hydrobromic acid is one of the strongest mineral acids known.
A redox reaction of hypobromous acid (HBrO) can form bromous acid (HBrO 2) as its product: [citation needed] HBrO + H 2 O − 2e − → HBrO 2 + 2H + The disproportionation reaction of two equivalents hypobromous acid (HBrO) results in the formation of both bromous acid (HBrO 2) and hydrobromic acid (HBr): [citation needed] 2 HBrO → HBrO 2 + HBr
In organic chemistry, free-radical halogenation is a type of halogenation. This chemical reaction is typical of alkanes and alkyl-substituted aromatics under application of UV light. The reaction is used for the industrial synthesis of chloroform (CHCl 3), dichloromethane (CH 2 Cl 2), and hexachlorobutadiene. It proceeds by a free-radical chain ...
In organic chemistry, free-radical addition is an addition reaction which involves free radicals. These reactions can happen due to the free radicals having an unpaired electron in their valence shell, making them highly reactive. [1] Radical additions are known for a variety of unsaturated substrates, both olefinic or aromatic and with or ...
The radical groups can then interact with HBr to produce a Br radical, which then reacts with the double bond. Since the bromine atom is relatively large, it is more likely to encounter and react with the least substituted carbon since this interaction produces less static interactions between the carbon and the bromine radical.
Radicals can undergo a disproportionation reaction through a radical elimination mechanism (See Fig. 1). Here a radical abstracts a hydrogen atom from another same radical to form two non-radical species: an alkane and an alkene. Radicals can also undergo an elimination reaction to generate a new radical as the leaving group.
