How can electronegativity be used to determine the type of bond?

It can determine if a molecule is polar or not...

Explanation:

Electronegativity difference between two atoms in a bond can determine what type of bond is used. Note that this usually only applies to covalent and ionic bonds.

The general rule is that:

$\Delta \text{EN">2, "the bond is ionic}$

$0.5 \le \Delta \text{EN"<2, "the bond is polar covalent}$

$\Delta \text{EN"<0.5, "the bond is non-polar covalent}$
