Well for hydrofluoric acid we could use, #""^(delta-)F-H^(delta+)#

Explanation:

Where the #delta# symbol denotes a little bit of (or partial) positive or negative charge. Dipoles are drawn from positive to negative. The overall dipole moment is the vector sum of the individual dipoles. And thus molecules such as #CF_4# or #"C"Cl_4# are NON-POLAR because the vector sum of the individual #C-X# dipoles is ZERO.

On the other hand, #CHCl_3,"chloroform"#, a common laboratory solvent is POLAR, because the vector sum of the #CrarrX# dipoles is NON-ZERO.
