Title: Difference between ionic bonding and ion-dipole forces
Post by: integral0 on February 09, 2005, 10:16:14 PM

I've been trying to understand the difference between ionic bonding and ion-dipole forces?  What is the big difference between them?  I couldn't quite tell...how to differentiate them.

Any help is appreciated thanks.

ionic bonding is what holds oppositely charged ions in a lattice together.

ion-dipole bonding describes a form of intermolecular bonding between molecules and ions. polar molecules contains dipole. due to non-uniform distribution of electron density in a molecule, the positive end of the dipole has less electron density and the negative end has more electron density. in a way, you can imagine each dipole end as a pseudo-ion. ions will be attracted to oppositely charged dipole ends.
