WebJul 14, 2024 · Aqueous solutions of HBr or HI (but not HCl) tend to cleave ethers into alcohol and an alkyl halide product by either an S N 2 or S N 1 mechanism. If the ether is attached to only primary, secondary, or methyl alkyl groups, a selective cleavage will … WebMay 28, 2015 · 7. 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.
