Carbon diselenide (Cse2) is a liquid at room temperature. The normal boiling point is 125C as well as the melting point is -45.5C. Carbon disulfide (Cs2) is as well a liquid at room temperature with normal boiling as well as melting points of 46.5C and -111.6 C, respectively. How do the strengths of the intermolecular forces vary from CO2, to Cs2, to CSe2. Explain
