Instantaneous dipole-induced dipole

Vedclass · Answer

(B) Inert gases are monoatomic and non-polar in nature.Since they lack permanent dipoles,the only attractive forces present between their atoms are weak London dispersion forces,also known as instantaneous dipole-induced dipole forces.These forces arise due to the temporary fluctuation in electron density,which creates a temporary dipole that induces a dipole in the neighboring atom.Therefore,these forces are responsible for the liquefaction of inert gases at very low temperatures.

Gas	$Ar$	$Ne$	$Kr$	$Xe$
$a \ (atm \ dm^6 \ mol^{-2})$	$1.3$	$0.2$	$5.1$	$4.1$
$b \ (10^{-2} \ dm^3 \ mol^{-1})$	$3.2$	$1.7$	$1.0$	$5.0$

Which intermolecular force is most responsible for the liquefaction of inert gases?
