Intermolecular Forces in CO2

Postby Sarah Zhari 1D » Mon Nov 18, 2019 8:37 pm

What are the intermolecular forces present in CO2? Does a non-polar molecule with polar bonds have dipole-dipole interactions?

Since CO2 is a nonpolar molecule, only London dispersion forces are present and therefore would not have dipole-dipole forces. The behavior of the bonds within the molecule, also known as intramolecular forces, does not determine the type of intermolecular forces.

CO2 only has London dispersion forces, or induced dipole - induced dipole interactions. Even though CO2 has polar bonds, the molecule is nonpolar because the dipoole moments cancel out. A nonpolar molecule cannot have dipole-dipole interactions. Only polar molecules can.

CO2 only has induced dipole-induced dipole interactions (every molecule has this). Since the dipoles cancel out, there is no dipole-dipole interactions.

Only London dispersion forces since it is a non-polar molecule.
