In ionic compounds, there is a complete transfer of electrons from one atom to another, resulting in the formation of ions. The electrostatic attraction between the positively and negatively charged ions holds the compound together.

The compounds that do not contain covalent bonds are:

- \(\text{O}_2\): This is a covalent compound because the two oxygen atoms share electrons to form a double bond.

- \(\text{LiCl}\): This is an ionic compound because the lithium atom transfers its valence electron to the chlorine atom, resulting in the formation of Li+ and Cl- ions.

- \(\text{SO}_2\): This is a covalent compound because the sulfur atom shares electrons with the two oxygen atoms to form two double bonds.

Therefore, the compound that does not contain covalent bonds is \(\text{Hl}\) and \(\text{CBr}_4\).
