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.

Hydrogen bromide is the inorganic compound with the formula HBr. 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. Aqueous solutions that are 47.6% HBr by mass form a constant-boiling azeotrope mixture that boils at 124.3 °C. Boiling less co… WebVideo transcript. Normally ethers are very unreactive, which is what makes them good organic solvents. However, if you react them with strong acids, you get acidic cleavage of the ether. So if we start with our ether over here on the left, and we add excess hydrogen halide, and we heat things up, the ether gets cleaved to form an alcohol and an ...
