How do the physical and chemical properties of calcium iodide (cai2) compare to carbon disulfide (cs2) and sodium fluoride (naf)?

Sodium fluoride and calcium iodide are ionic and carbon disulfide covalent.

Explanation:

Hello,

Since both calcium iodide and sodium fluoride are ionic compounds, one could identify that in comparison with carbon disulfide which is covalent:

- they've got both a cation and an anion.

- they are crystalline solids.

- they've got higher fusion points due to stronger electrostatic attractive forces.

- they don't conduce the electricity when solid but do it when liquid or in aqueous phase solutions.

Unlike sodium fluoride and calcium iodide, carbon disulfide:

- doesn't conduct the electricity.

- doesn't form charged particles in aqueous solutions.

- it tends to be liquid or gas due to weak intermolecular forces.

Best regards.
