Based on electronegativities, which bond of the following bonds is the most polar and which is the least polar? H-F, H-N, H-C, H-H, and H-O

Based on electronegativities H-F bond is most polar and H-H bond is less polar.

Explanation:

Electronegativity can defined as the ability of an atom to attract the bonding electron pair towards itself. This result in the generation of polarity.

H-F bond most polar because Fluorine is most electronegative among nitrogen, hydrogen and oxygen.

On the other hand H-H bond is least polar or nonpolar because the boding electron pair are equally shared by the two hydrogen atoms.
