Assign partial charges (electronegativity) to all atoms within the molecule, based on the “flow of electrons'“
Determine whether each bond is polar or non polar. If the molecule has no polar bonds or it is symmetrical, it is nonpolar.
Approx. Electronegativity Difference | Type of Bond | Example |
---|---|---|
0.0 - 0.4 | Covalent (non polar) | H-H |
0.4 - 1.0 | Covalent (moderately polar) | H-Cl |
1.0 - 2.0 | Covalent (highly polar) | H-F |
>2.0 | ionic |
