The strength of an acid is proportional to the number of molecules and ions that are present in the acid solution. The stronger the acid the more ions that are present and the weaker the acid the more molecules that are present. Because there are more ions present in a strong acid, stronger acids are better conductors of electricity. But what does acid strength have to do with bond strength. In a strong acid molecules are easily broken apart into ions, and therefore, the bond strength is weak. However, in a weak acid molecules are not easily broken apart into ions, and therefore, the bong strength is strong. Consequently:

Strong acid = more ions = weak bonds = better conductivity
Weak acid = less ions = strong bonds = poorer conductivity

Therefore, because HCl has the weaker bonds, it is more conductive than HF.
