Strongest/weakest intermolecular forces

Postby Melody Haratian 2J » Thu Nov 19, 2020 1:56 pm

Hi guys!
Can someone let me know the order of intermolecular interactions from weakest to strongest?
I get them confused a lot of times.
Thanks!

Ionic bonds > Hydrogen bonding > Dipole-dipole interactions > London dispersion forces

To add onto that, it's ion-ion>ion-dipole (just to be more specific about the ionic bonds)

Could covalent bonds be a part of this list?

Covalent bonds are intrAmolecular forces! That exist within the molecule!

Here's the list of intermolecular forces in the order of increasing strength (from weakest to strongest):
- LDF (induced dipole-induced dipole)
- dipole-induced dipole
- dipole-dipole
- ion-dipole
- hydrogen bonding
- ion-ion

I wasn't sure if hydrogen bonding or ion-dipole was stronger, thank you for this list!
