The force of attraction holding Carbon Dioxide together?

Question

What does the melting poiint and boiling point tell us about the forces of attraction that are holding carbon dioxide's molecules together? Thanks! :)

Answer 1

Nothing in general. The molecule is held together by electron bonds. However, CO2 as a substance does not have extra-molecular attraction of molecules WITH EACH OTHER, and thus is a gas at room temperature. Moreover, its relatively high pressure associated with its triple point (this point determines the onset of the liquid phase) is another feature of ths lack of attraction.

Answer 2

The answer is actually Hydrogen bonding. The intermolecular forces of hydrogen bonding hold together the water molecules stopping them from becoming gaseous. If it wasnt for hydrogen bonding then water would actually be a gas!
