Which of the following substances would you expect to have the lowest boiling point? A) potassium nitrate, KNO₃ B) sodium C) ethane, C₂H₆ D) glycerine, C₃H₅(OH)₃ E) diamond

Question

Quizplus · Accepted Answer

Ethane has the lowest boiling point because it is a small non-polar molecule with weak intermolecular forces, making it easier to break the bonds between the molecules and causing it to boil at a lower temperature. The other substances have stronger intermolecular forces (ionic or hydrogen bonding) or are not even a substance that can boil (diamond).
