Carbon diselenide (CSe2) is a liquid at room temperature. The normal boiling point is 125oC, and the melting point is –45.58C. Carbon disulfide (CS2) is also a liquid at room temperature, with normal boiling and melting points of 46.5oC and –111.6oC, respectively. How do the strengths of the intermolecular forces vary from CO2 to CS2 to CSe2? Explain your answer.
