which has the weaker dipole forces?
CF3 or CH3F?
H20 or CO2?
SO3 or SO2?
AsCl3 or BCl3?

CF3 is trigonal planar with three of the same atoms attached to C while CH3F is tetrahedral with 3H and 1F, which means that there will be a strong dipole between the C and F.
The clue for the others is in the geometry...is the molecule linear or bent? If bent, will be greater dipole forces. Does the molecule have unshared electron pairs? If so, the dipole will be greater.

If i remember correctly, these all have dipole-dipole forces. Therefore, now you have to look at the sizes of the compounds themselves. The larger the compound, the weaker the dipole forces is, hoped that help
