ion-ion bond vs. H-bond

Postby Cecilia Jardon 1I » Tue Nov 27, 2018 9:27 pm

What type of intermolecular forces would be stronger? An ion-ion or an H-bond and why?

An ion-ion bond would be an ionic bond, which is the strongest type of bond. This is because it is based on the transfer of electrons, whereas an H bond is more like an electrostatic attraction between a proton and lone pair. This is also evidenced by the high melting/boiling points of ionic substances, higher than those with h-bonds.

Ion-ion bonds are stronger than hydrogen bond. Ion-ion bonds result in solids as seen in an example with Na+ and Cl-. Together Na+ and Cl- will form an ordered lattice. Hydrogen bonding comes second as this is still the strongest type of intermolecular forces since the difference in electronegativity is high between a H and atoms such as F, O, or N. Molecules with hydrogen bond have high boiling/melting points and typically will be in form of a liquid.

ion-ion bond is the strongest bond because it is ionic, however an ionic bond in water is weaker than a covalent bond but still stronger than a hydrogen bond

This is good information because I was wondering the same thing.
