Why are hydrogen bonds the strongest of the intermolecular forces?

Yes.

A hydrogen bond works with only Fluorine, Oxygen and Nitrogen. If we take a look at the period table and remember the trends for electronegativity we see that these 3 elements are among the most electronegative, in which fluorine has the highest electronegativity.

Hydrogen has a + charge, so the attraction between the hydrogen and the 3 elements is very strong. Hence, hydrogen bonding is very strong. This is the type of attraction that occurs in our DNA.

Whereas, Diapoles are only partial charges based on where the highest density of electrons is in the moment.

because they are formed with the 3 most electronegative atoms F N and O. they attract the electron density the most.

There isn't a certain reason for this. You just have to memorize it.

They form with the most electronegative elements, and it's with hydrogen, which is low electronegativity
