WebHydrobromic acid is a strong acid formed by dissolving the diatomic molecule hydrogen bromide (HBr) in water. "Constant boiling" hydrobromic acid is an aqueous solution that … WebMay 28, 2015 · 1 Answer. Cleavage of ethers using strong acids (classically H I but H B r should work as well) can proceed by either an S N 1 or S N 2 mechanism. In this case the cation formed would be primary or phenyl, neither of which are stable, and so the reaction proceeds via an S N 2 mechanism. The oxygen is protonated in an equilibrium reaction.
