### In hydrogen iodide __________________ are the most

May 06, 2019The most important attractions between HI molecules are London dispersion forces. The strength of London dispersion forces is proportional to the polarizability of the molecule, which in turn, depends on the total number of electrons and the area over which they are spread. HI has 54 electrons and is larger than any of the other HX molecules.
