Every book I've read attributes the rise in boiling points from HCl to HI as due to increased molar mass; this site attributes it to increased London forces due to the larger number of electrons.
http://en.wikipedia.org/wiki/Hydrogen_halide
1) The order of the boiling points for the hydrogen halides, except for HF, is
HI > HBr > HCl. The reason for this order can be attributed to
a) the relative covalent bond strengths.
b) differences in hydrogen bonding.
c) differences in dipole-dipole attractions.
d) differences in London forces.
e) differences in dipole/induced dipole interactions
I chose answer e, dipole/induced dipole interactions. Is this correct?
