I made this graph:
First of all my book said that it should be obvious that the fractional distillation resulted in a better separation of the two liquids in my unknown. But to me both the simple and fractional distallation graphs look the same to me! Anyway....
It says that I should be able to estimate the boiling points of the two components in my unknown mixture based on the graph. The temp. should level off on two regions of the graph.
I don't see it though?
These are the possible compounds:
Hexane (BP 69 degrees celsius)
Cyclohexane (80.7)
Heptane (98.4)
Toluene (110.6)
Ethylbenzene (136)
I'm guessing Hexane and Cyclohexane but don't think my reasoning is correct.
