Does a greater difference in EN correlate to a stronger bond
If there is a greater difference in electronegativities between atoms present in an ionic bond, is that bond considered "stronger"? Does the same concept apply to covalent bonds?

Generally, yes. A bigger difference in electronegativity indicates that the bond is more ionic. Since ionic bonds are known to have strong bonding characteristics, it makes sense that the more ionic a bond is, the stronger the bond.

Yes, this also applies to covalent bonding as well. The larger the electronegativity difference, the stronger the covalent bond tends to be. For example, a C-Cl bond with an electronegativity difference of .5 has a bond strength of 338 KJ/mol, whereas C-Br bond with an electronegativity difference of .3 has a bond strength of 276 KJ/mol.
