A hydrogen bond is a very strong dipole-dipole bond. A hydrogen bond can only form between hydrogen and a strong electromagnetic atom; fluorine, oxygen or chlorine.
When the range of electronegativity between the atoms are really high. For example, hydrogen has 2.20 elctronegativity and fluorine has 3.98 and the range between them is 1.78. Compared to like nitrogen (3.04) and oxygen (3.44), whose range is 0.4, the hydrogen and fluorine will have a strong dipole-dipole force.
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.
An overall dipole moment is H2S.
Dipole means that there's an uneven distribution of electrons in a molecule; this usually occurs when you've a molecule with atoms of very different electronegativities. Covalent describes bonds that have electrons shared between atoms. The opposite of this would be ionic, where one atom takes electrons from another atom.
