In this video we’ll identify the intermolecular forces for CO2 (Carbon dioxide). Using a flowchart to guide us, we find that CO2 only exhibits London Dispersion Forces since it is a non-polar molecule. • In determining the intermolecular forces present for CO2 we follow these steps: • Determine if there are ions present. Since there is not + or – sign after the CO2 we can say that it is not an ion. • Next, based on its Lewis Structure, we determine if CO2 is polar or non-polar (see • Is CO2 Polar or NonPolar? ). Since there Carbon dioxide is a symmetrical molecule the dipoles cancel out and there is no net dipole. Therefore CO2 is a non-polar molecule. • Because CO2 is non-polar it will only exhibit London Dispersions Forces. • Useful Resources: • Determining Polarity: • Polar, Non-Polar, and Ionic Compounds... • Drawing Lewis Structure: • How to Draw Lewis Structures: Five Ea... • Molecular Geometry: • Molecular Geometry: Rules, Examples, ... • More chemistry help at http://www.Breslyn.org
