Hydrogen Bonds

Postby Maggie Eberhardt - 2H » Sun Nov 17, 2019 1:09 pm

Are hydrogen bonds the strongest IMF? I'm pretty sure they are but I don't 100% understand why?

Hydrogen bonds are extremely powerful. This is because an extremely electronegative atom, such as O, pulls the electron on the Hydrogen atom towards them, leaving the H side partially positive. This partial positive H can react with the partial negative lone pairs of the O of another molecule.

Hydrogen bonds are the strongest types of dipole-dipole interactions. Ion-ion are the strongest type of IMF!

Yes, hydrogen bonds are the strongest IMF. The δ+ hydrogen is so strongly attracted to the lone pair on the other atom that it is almost as if you were beginning to form a covalent bond. It doesn't go that far, but the attraction is significantly stronger than an ordinary dipole-dipole interaction.
