Question:

Identify the inter-molecular forces present in each of these substances.

Answer & Explanation:

Intermolecular Forces:

Intermolecular forces are the attractive forces that occur between molecules. These include London dispersion forces, which all molecules have, dipole-dipole interactions, hydrogen bonding, and ion-dipole interactions. Dipole-dipole interactions occur between molecules that are polar and hydrogen bonding occurs between polar molecules with a hydrogen bonded to a N, F, or O. Ion-dipole interactions occur between ionic and polar compounds.

Answer and Explanation:

The intermolecular forces in H2O are London dispersion forces, dipole-dipole interactions, and hydrogen bonding. All molecules have London dispersion forces. Water is polar, so it will experience dipole-dipole interactions. Water also has a hydrogen with a bond to oxygen, so it will have hydrogen bonding as well.

The only intermolecular force present in He is London dispersion forces. It is a nonpolar molecule, so it will not experience any other force.

CH3Cl will experience both London dispersion forces and dipole-dipole interactions because it is a polar molecule.

CO is also a polar molecule, so it experience London dispersion forces and dipole-dipole interactions.
