How to tell the difference between octane-1-ol and oct-1-ene? How to tell the difference between octane-1-ol and oct-1-ene? The things I can do are:


check their solubility in water
use bromine water
use $\ce{KMnO4}$
use sulfuric acid


I assumed that checking the solubility would be a good idea because of the presence of an alcohol but will I notice a difference since the alcohol has 8 carbon atoms. And they all react with bromine water, $\ce{KMnO4}$ and $\ce{H2SO4}$. I think I'm missing something.
Alkene is best characterized, then, by its property
of decolorizing both a solution of bromine in carbon tetrachloride  and
a cold, dilute, neutral permanganate solution (the Baeyer test). Both
tests are easily carried out; in one, a red color disappears, and in the other, a purple color disappears and is replaced by brown manganese dioxide.
