Hexane on top of water?

Vigorouschemist Chemistry Supervisor
Yes. If you put water and hexane in a beaker or a container together, the hexane will be on top of the water. One way to see this is to dye the water. They do not mix because water is polar and the hexane cannot dissolve in it. It is on top because, guess why? It is less dense than water. That is why anything floats on water... it is less dense! Hope that answers your question!

Hexane solube in water?

NO Hexane will phase separate when added to water. The hexane will form the top layer , as it is lighter than water
