Explain why the boiling point of Br2 (59°C) is lower than that of iodine monochloride, ICl (97°C), even though they have nearly the same molar mass.Choose one: A.  Br2 is larger than ICl. B.  The molar mass is not identical: the molar mass of Br2 is only 159.80 g/mol compared to 162.35 g/mol for ICl. C.  ICl is ionic. D.  ICl is polar while Br2 is nonpolar.
