Answer to Question #85134 in General Chemistry for Jasmine

Question

Which of the following diatomic gases would be expected to have a boiling point very close to the boiling point of the monatomic noble gas Ar?

Answer 1

Argon is the most abundant of the truly inert or "rare" gases. It is produced, most commonly, in conjunction with the manufacture of high purity oxygen using cryogenic distillation of air. Since the boiling point of argon is very close to that of oxygen (a difference of only 5.3°F or 2.9°C) separating pure argon from oxygen (while also achieving high recovery of both products) requires many stages of distillation.

-302.53 °F -185.85 °C, Argon Boiling point 87.30 K,

-297.31 °F -182.95 °C, Oxygen Boiling point 90.20 K,

-29.27 °F -34.04 °C, Cl2 Boiling point 239.11 K,

−306.62 °F −188.12 °C, F2 Boiling point 85.03 K,
