why does chlorobenzoic acid have a lower freezing point than benzoic acid explain?

Question

would this have something to do with the intermolecular forces or polarity. I know that the chlorobenzoic acid a Cl atom in the molecule which would create for a stronger intermolecular force but I'm not to sure how this could account for a lower freezing point?

Answer 1

Hmmmm. Please examine the fp for benzoic acid and chlorobenzoic acid.
