chart of intermolecular forces including polar, nonpolar, etc

[00945584]

is this correct according to strength?

ionic>covalent>ion-dipole>hydrogen bond>dipole-dipole>dipole-induced dipole>london dispersion

but then if a molecule is polar and another molecule is nonpolar then for ex. does the polar molecule have a higher bp.

so a polar molecule can be considered as dipole-dipole?
and nonpolar as london dispersion?

is my logic right.

Yes the polar molecule will have a higher bp. logic seems right. On the MCAT, the importance of H-bond is critical. In the answer choices, the one answer with the most hydrogen bonds should have the highest boiling point.

provided they are all non ionic answer choices ..........

More polar/more H-bonding between compounds with a similar molecular weight = higher BP.

right. I corrected my above statement to read "non-ionic".

Can covalent bonded molecules also have Hydrogen bonding?

I thought on the mcat that covalent, ionic, and metallic bonds were intramolecular

while hydrogen could be in both

and then intermolecular was dipole-dipole(van der walls) and dispersion (London)
