Question

You are given three test tubes that contain colourless liquid. One test tube contains benzene, another contains ethanol, and the third contains 2,4-hexadiene. Design a procedure that will tell you the contents of each test tube. Describe your expected observations.

So benzene is an aromatic, ethanol is an alcohol, and hexadiene is an alkene. I'm not sure where to go from here.. please help :)

Answer 1

Try using this information. Ethanol dissolves in water. Does benzene? Does 2,4-hexadiene?
The diene adds Br2 to it easily. What can you do with that?

Answer 2

hmmmm..
well what methods should i be using?
should i add water to each of them, and i will know that the only homogenous mixture is ethanol. Then I could add Br2 to the remaining ones, and the 2,4-hexadiene will be uniform, leaving me with the benzene?
am i on the right track?
