Ionic compound

Explanation:

Na2O

This is an ionic compound because it contains a metal (Sodium) bonded to a non metal (Oxygen).

Copper

Atomic Element

Nitrogen

Atomic Element

Co3O4

This is an ionic compound because it contains a metal (Cobalt) bonded to a non metal (Oxygen).

N2O

This is a molecular compound because it contains a non metal (Nitrogen) bonded to a non metal (Oxygen).

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
