How to tell the difference in between octane-1-ol and also oct-1-ene? The points I deserve to do are:

check their solubility in wateruse bromine wateruse $\ceKMnO4$use sulfuric acid

I assumed that checking the solubility would be a good idea since of the presence of an alcohol yet will I notice a difference due to the fact that the alcohol has 8 carbon atoms. And they all react with bromine water, $\ceKMnO4$ and $\ceH2SO4$. I think I"m lacking something.

You are watching: How could you distinguish 1-octanol from 1-octene by a simple chemical test



Alkene is finest characterized, then, through its propertyof decolorizing both a systems of bromine in carbon tetrachloride anda cold, dilute, neutral permanganate solution (the Baeyer test). Bothtests are easily brought out; in one, a red shade disappears, and also in the other, a purple shade disappears and also is changed by brown manganese dioxide.


See even if it is in enhancement of Br₂ in CCl4 it gives red color or no ,It is a test to view the presence of the twin bond and also you can shot Lucas check on the alcohol


In a decent university lab you could shot treatment with ozone, followed by triphenyl phosphine or reduction through zinc / acetic acid and then vapor distillation. The octene will type formaldehyde and heptanal when the octanol should do nothing.
