    Which of the following molecule has a higher dipole-dipole force (not taking account the London's dispersion force), HI or HCl

    We all know that HI has a higher boiling point than HCl, but is that due to the dispersion force or the dipole-dipole force?

    I am confused!

    HCl got the biggest dipole interaction but HI have the biggest mass so its rather more liquid by that
