WebSep 24, 2024 · Acidic Cleavage of Ethers. 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 typically take place using an S N 2 mechanism. First, the strong … WebDimethyl ether (DME) is the well-fit candidate to substitute LPG because of its properties similarities.
