4.
CH4:
CH4
5.
Li2O:

Answer 1

Step-by-step explanation

NaCl: Ionic crystal lattice forces

Hg: Metallic bonding

CO₂: London dispersion forces

CH₄: London dispersion forces

Li₂O: Ionic crystal lattice forces

Ag: Metallic bonds

Ionic crystal lattice forces are strong electrostatic force of attraction between oppositely charged ions arranged into a crystal lattice of ionic compound. NaCl and Li₂O are ionic compounds

London dispersion forces holds the molecules of carbon dioxide and methane. They are weak attractions found between non-polar (and polar) molecules.

Metallic bonds exists between Mercury and Gold atoms. This is due to sea of electrons present.
