Consider the compounds Cl2, HCl, F2, NaF, and HF. Which compound has a boiling point closest to that of argon? Explain how you c
Ipatiy [6.2K]

Answer:

Cl2, Chlorine molecule has a boiling point closest to that of argon.

This is because Chlorine is made up of discrete and simple molecules making up a simple molecular structure. The molecules associate through weak van der waal's forces of attraction hence low boiling point.

HCl <em>has</em><em> </em><em>strong</em><em> </em><em>hydrogen</em><em> </em><em>bonds</em><em>.</em>

F2 <em>is</em><em> </em><em>very</em><em> </em><em>small</em><em> </em><em>hence</em><em> </em><em>strong</em><em> </em><em>forces</em><em> </em><em>of</em><em> </em><em>attraction</em><em>.</em>

HF <em>has</em><em> </em><em>strong</em><em> </em><em>hydr</em><em>ogen</em><em> bonds</em>
