Concept introduction:

The nature of the compound depends on the difference in the electronegativity of two atoms. The given compound is considered as a non-polar covalent compound if the electronegativity difference between two atoms is less than 0.5. If the electronegtaivity difference is between 0.5 to 1.7 then the bond is polar covalent in nature. If the difference is more than 1.7, the bond between two atoms will be ionic in nature.
