Homework Help: Chemistry(Please check)

1) For a series of small molecules of comparable molecular mass, which of the following choices lists the intermolecular forces in the correct increasing order?

a) dipole-dipole forces < London forces < hydrogen bonds
b) hydrogen bonds < dipole-dipole forces < London forces
c) dipole-dipole forces < hydrogen bonds < London forces
d) London forces < dipole-dipole forces < hydrogen bonds
e) hydrogen bonds < London forces < dipole-dipole forces

I chose answer A because dipole-dipole forces are weaker than london forces and london forces are weaker than hydrogen bonds.

Is this correct?

No, London forces are the weakest. Weaker than hydrogen bonds and weaker than dipole-dipole.

O ok so it is london forces,dipole,then hydrogen?

That's what I would choose. Here is a good site that compares strengths. Scroll down to that part.
