Which compound has greater intermolecular interactions, CO or CO2(the 2 is, of course, a subscript)?

Answer 1

I agree with Stephan B.
I would like to expand his answer a bit so that it is more clear.
CO has a polarized bond because of the electronegativity of oxygen and thus is a dipole.
CO2 is linear because the stucture is O=C=O. So although both bonds are polarized the momentum of one cancels out completely the other (same type of bond and 180 deg angle). Thus the molecule is not polar.

Although CO2 is bigger and thus the Van der Waals forces will be stronger for it than for CO, dipole-dipole forces are much stronger than Van der Waals forces and thus CO which has dipole-dipole forces between its molecules will exhibit stronger intemolecular interactions.

Answer 2

Difficult to say, I'd perhaps think the Carbon monoxide would have more, as it is a polar molecule so you'd get dipole-dipole interactions to a greater degree than in Carbon dioxide

Answer 3

CO will combine readily with more O to form CO2.( or with hemoglobin in your blood to form carboxyhemoglobin) CO2 is a stable molecule.

Answer 4

CO2

Answer 5

Enjoyed this question

Answer 6

always when I submit a question, even if it's the easiest one, they can't offer me a good informed answer . Wtf happened to people that really take the time to write an answer?
