How are we supposed to approach this problem? the only thing I can think of is that if the bond lengths are shorter then the attraction is greater.

First, you would try to figure out what atoms correspond to which color. So looking at the diagram, the dark grey atom would be carbon because it is the central atom. Then, the light grey atom would be hydrogen because hydrogen is smaller than chlorine. So then that leaves the green atom to be chlorine. Then the arrangement with the strongest intermolecular force would be the one with the strongest dipole-dipole interactions. So you would look at the placement of the molecules and make sure there is no electron-electron repulsion.

I think the bond lengths are all the same, we should be looking at the dipole moments for the atoms and how they face the dipoles of other atoms
