If a questions ask about forces between molecules, it's talking about INTERmolecular forces-(How will I remember this? Maybe INTERmolecular forces are to molecules and compounds as INTERstates are to different states...)
INTERmolecular forces are-- strongest to weakest
1. covalent bonds
2. hydrogen bonding
the next two are van der Waals
3. dipole dipole
4. London dispersion forces
Distinguishing b/w dipole & covalent:
I suspect, from AAMC7, it's difficult to predict whether a compound exhibits covalent or dipole-dipole bonds (or both) just by looking at it. But given that covalent bonds are really strong, a really low boiling point likely means that they are not around. ?
London dispersion forces:
Are they always around?
INTRAmolecular bonds
Ionic, metallic & covalent
2 questions:
Is what I have written from strongest to weakest?
And are covalent bonds then intramolecular and intermolecular forces?
