"WebPredict which will have the higher boiling point: ICl or Br 2. Explain your reasoning. Answer: ICl. ICl and Br 2 have similar masses (~160 amu) and therefore experience similar London dispersion forces. ICl is polar and thus also exhibits dipole-dipole attractions; Br 2 is nonpolar and does not.
