Which of the following molecules has polar bonds and is nonpolar?
Look up the electronegativity of H and F, for example. H is 2.1, F is 4.0, subtract them to get a difference of 1.9 so HF is polar. Strictly speaking, there are no non-polar bonds in those compounds listed. The difference in electronegativity must be zero to have a non-polar bond. ICl3 probably comes the closest to being non-polar but the difference is not zero.
