# how do we determine whether a given molecule is polar or non polar on a basis other than electronegativity ?

Dear Student

To determine the polarity of a covalent bond using numerical means, the difference between the electronegativity of the atoms is taken. If the result is between 0.4 and 1.7 then, generally, the bond is polar covalent.
Atoms with high electronegativities Ã¢Â€Â” such as fluorine, oxygen, and nitrogen Ã¢Â€Â” exert a greater pull on electrons than atoms with lower electronegativities. In a bonding situation this can lead to unequal sharing of electrons between atoms, as electrons will spend more time closer to the atom with the higher electronegativity.

We hope that clarifies your query.
