WebbVideo 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 ...
