London dispersion forces.
Explanation
To identify the type(s) of intermolecular forces between CO2 molecules, we need to consider the molecular structure and properties of carbon dioxide (CO2). CO2 is a linear molecule with oxygen atoms bonded to a central carbon atom. It is a nonpolar molecule due to its symmetrical linear shape, which causes the dipole moments from the C=O bonds to cancel out.Intermolecular forces are the forces that mediate interaction between molecules, including ionic, hydrogen bonding, dipole-dipole, and London dispersion forces.1. Ionic Bonds: These occur between positively and negatively charged ions. CO2, being a non-ionic molecule, does not have ionic bonds. 2. Hydrogen Bonds: For hydrogen bonds to occur, a molecule must contain a hydrogen atom attached to a highly electronegative atom (like F, O, or N). Since CO2 does not contain hydrogen bonded to highly electronegative atoms, hydrogen bonding is not present. 3. Dipole-Dipole Forces: These occur between polar molecules. CO2, being nonpolar, does not exhibit dipole-dipole interactions. 4. London Dispersion Forces: These are present in all molecules, whether polar or nonpolar. They are caused by the temporary dipoles that occur due to momentary uneven distribution of electrons within molecules. In the case of CO2, London dispersion forces are the only type of intermolecular forces present.Thus, the only type of intermolecular force in CO2 is London dispersion forces.
