CS2 is a molecular compound, CuO and KI are ionic compounds, and PCl3 is a molecular compound.

The compounds CS2, CuO, KI, and PCl3 can be classified as follows:

CS2: Molecular compound. This compound is made up of two nonmetals: carbon and sulfur. They share electrons and form covalent bonds.
CuO: Ionic compound. This compound is made up of a metal (copper) and a nonmetal (oxygen). The metal donates electrons to the nonmetal, resulting in the formation of ionic bonds.
KI: Ionic compound. This compound is made up of a metal (potassium) and a nonmetal (iodine). The metal donates electrons to the nonmetal, resulting in the formation of ionic bonds.
PCl3: Molecular compound. This compound is made up of a nonmetal (phosphorus) and a halogen (chlorine). They share electrons and form covalent bonds.
