Question
thumb_up100%
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.
E. It is impossible to say without further information.
F. The molar mass dependence of a liquid's boiling point is not an absolute rule, and it should not be applied to all of the compounds.
