Explanation:

Propane ($C_3H_8$) is a covalent - molecular compound. Covalent bonds hold the carbon and hydrogen atoms together within a propane molecule. In the condensed state (liquid or crystal), van der Waals forces bind separate propane molecules together. There are no ionic or metallic bonds involved in propane.

Answer:

Van der Waals, Covalent
