What's the cut off point between polar and nonpolar in terms of electronegativity?

Polar bonds mean that there is electronegativity difference, and nonpolar bonds don't have an electronegativity difference, like N2. Hope this helps!

There isn't a cut off in polar and non-polar molecules as a polar molecule. But, for covalent bonds the difference in electronegativity is less than 1.5 and for ionic bonds the difference in electronegative is greater than 2.

You can consider that bond is polar if there are a difference in electronegativity. If the electronegativity is different, it means that there are difference in how much the nucleus will pull the shared electron towards it.

Nonpolar bonds don't have different electronegativities, whereas polar bonds do. For example, H20.
