Rank the intermolecular forces in order from strongest to weakest?

Answer 1

The strongest intermolecular force is Hydrogen Bonding! Hydrogen atoms have a very strong attraction to Fluorine, Oxygen, and Nitrogen atoms, a molecule with Hydrogen and a molecule with F, O, or N will form strong hydrogen bonds. Just remember FON or NOF.

(It's important to note that hydrogen bonding does NOT occur with hydrogen atoms that are bonded to carbon atoms.)

The second strongest is dipole-dipole attraction. Some molecules are polar, meaning they have a positive and negative pole, kind of like magnets. And just like magnets, two polar molecules attract because one's negative pole is attracted to the other's positive pole.

The weakest of them all is London Dispersion force. This force exists between all molecules, no matter what atoms are in them. Basically, as electrons fly around the nuclei of atoms, they'll often create a very weak dipole that exists only for a tiny fraction of a second. Basically these LD forces are just like D-D forces except weaker.
