Comparing Strength of Hydrogen Bonds

Postby Anisha Chandra 1K » Thu Nov 21, 2019 8:36 am

If you have 2 molecules with hydrogen bonding, how can you tell which one is stronger?

The molecule with more hydrogen bonds will be stronger. But you can also argue the molecule with stronger London dispersion (induced-induced dipole) forces will be stronger overall. Strong dispersion forces means that the atom compared is bigger (so more electrons), so larger polarizability, and therefore stronger dispersion forces.

Return to “Interionic and Intermolecular Forces (Ion-Ion, Ion-Dipole, Dipole-Dipole, Dipole-Induced Dipole, Dispersion/Induced Dipole-Induced Dipole/London Forces, Hydrogen Bonding)”
