Answer 2

Answer:

E.N. difference Type of bond

0 Nonpolar covalent

0-1.6 Polar covalent

1.7 50% covalent , 50% ionic

1.7-3.3 Mainly ionic

It is the Gallis scale that explains the type of bond with E.N. difference,

so the compound XY would be ionic if the E.N. difference between X and Y is more than 1.7.
