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.
