Polar character in a molecule is related with the electronegativity differences between the atoms of a given chemical species.
For example, water molecule is polar because the existence of a dipolar moment due to differences between electronegativities among oxygen and hydrogen atoms.
Considering this definition, fluorine gas (F2) (I affirm that is gas because a Fluorine ion is hard to exist in normal conditions) is less polar in aquous solution than Benzoic Acid because electronegativity differences between fluorine atoms (F - F) in this molecule is zero, while difference of electronegativities in atoms of Benzoic acid (C6H5 - COOH) is higher than zero due to the presence of the oxygens in carboxilic group.
Hope it helps!
Good luck!

Are you talking about fluorine atom (F) or fluorine molecule (F2)? I believe latter. F2 is a diatomic molecule and is non-polar. Benzoic acid is polar because of the carboxylic acid group,
-C(=O)-OH.
