I really hope this helps. H-F because the difference in electronegativity is larger, about 1.9 in the scale of Pauling. The term means that bond has the greatest polarity and therefore is more similar to an ionic bond, which involves the transfer of an electron (as opposed to covalent bonds, which share electrons). Is H-F, because out of all the atoms here bonded with H, that is to say, the hydrogen, F is the most electronegative which means that you can pull the bonded electrons to itself more than what can be Cl, S and N. Which means a strong polarization of the electron cloud forming the bond with the hydrogen and, therefore, a greater ionic character.
