Question

Xe gas can be liquified due to the :

• A. Ion - dipole interaction
• B. Dipole - dipole interaction
• C. Instantaneous dipole - induced dipole interaction
• D. None of the above

Answer 1

The correct option is C Instantaneous dipole - induced dipole interaction

A gas can be liquified only if it has significant intermolecular forces of attraction. $Xe$ is a non polar gas so an instantaneous dipole is created in one molecules which induces dipole in other $Xe$ molecule which is responsible for the liquefaction of $Xe$. Due to increases size and van der Waal force of $Xe$, it is easy to liquify at low temperatures.
