The Boiling Point of HCl (188 K) Is Lower Than

Multiple Choice

The boiling point of HCl (188 K) is lower than that for HI (238 K) because

A) HI is more polar therefore the intermolecular dipole-dipole forces are stronger in HI.
B) HCl is more polar therefore the intermolecular dipole-dipole forces are stronger in HI.
C) the molecular mass of HI is greater than that of HCl.
D) HI is more polarizable, dispersion forces compensate for the lower dipole forces in HI.
E) HI is capable of hydrogen bonding, HCl is not.
