Sam knows that he has one of 3 possible liquid unknowns: tetrahyrofuran (bp 65-67°C), ethyl acetate (bp 76-77°C), or toluene (bp 110-111°C). He sets up for a microscale bp determination and clamps the whole shebang in a water bath. Fifteen minutes late the water is boiling like crazy, but he has yet to see a single vapor bubble escape from the capillary tube. He double-checks his set-up and everything is fine so now he’s totally confused. What must his unknown be and why? Break it to him gently…he doesn’t want to feel like a total idiot.
