Increase in polarisability

Vedclass · Answer

(D) The boiling points of noble gases increase from $He$ to $Xe$ due to the increase in the magnitude of van der Waals forces of attraction.These forces are directly proportional to the size of the atom.As the atomic size increases from $He$ to $Xe$,the polarisability of the electron cloud increases.Therefore,the increase in polarisability leads to stronger dispersion forces,resulting in higher boiling points.

Which factor is most responsible for the increase in boiling points of noble gases from $He$ to $Xe$?
