Intermolecular Forces vs Bonding???

Postby KNguyen_1I » Wed Nov 13, 2019 3:47 pm

So we consider things like ion-dipole, LDF, dipole-dipole, etc as intermolecular forces right? So what do we call polar and nonpolar bonding between the atoms within the molecule? Or rather, in general, what are the relationships between these things?

Ion-dipole, LDF, and dipole-dipole, etc are intermolecular forces: forces between two different molecules meanwhile polar/nonpolar are intramolecular forces (within the molecule).
Also, dipole-dipole: interactions between 2 polar molecules
LDF: interactions between 2 non polar molecules

Those are known as intermolecular forces because they are the forces that attract different molecules to one another. Polar and nonpolar bonding occurs between atoms in a molecule so we call them intramolecular (since they happen within the molecule).

I'm still kind of confused on what a dipole moment is, can you help clarify?

Do all molecules have London Dispersion Forces and only certain ones have dipole moments (i.e. you must draw the lewis structure to see that).

Dipole moments are within mostly covalent compounds where the greater electronegative differences between the elements/atoms int the molecule create a slight polarity between the charges of the atoms and causing slightly ionic properties due to the electronegativity.
