explain why the boiling point of Br2 (59 degrees C) is lower than that of iodine monochloride, ICl (97 degrees C), even thought they have nearly the same molar mass A: Br2 is larger the ICl B: ICl is ionic C: the molar mass dependence of a liquid's boiling point is not an absolute rule, and it should not be applied to all compounds D: it is impossible to say without further informations E: 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 F: ICl is polar while Br2 is nonpolar
