Answer

Answer:

  • solid iodine: Both intermolecular and intramolecular
  • argon gas: Intermolecular only
  • liquid mercury: Intermolecular only
  • solid sodium chloride: Both intermolecular and intramolecular

Explanation:

Step1: Analyze solid iodine

Solid iodine ($I_2$) has covalent bonds (intramolecular) within the $I_2$ molecules and London - dispersion forces (intermolecular) between the molecules.

Step2: Analyze argon gas

Argon is a noble - gas. It exists as single atoms. There are no intramolecular bonds (as it is a single atom) but has London - dispersion forces (intermolecular) between the atoms.

Step3: Analyze liquid mercury

Mercury is a metal. In liquid mercury, there are metallic bonds which are a type of intermolecular force (metallic bonding is the attraction between metal cations and delocalized electrons), and there are no traditional intramolecular bonds as it is an element in a non - molecular form.

Step4: Analyze solid sodium chloride

Solid sodium chloride ($NaCl$) has ionic bonds (intramolecular) between $Na^+$ and $Cl^-$ ions and also has ion - ion interactions (intermolecular) between the formula units in the crystal lattice.
