    Which one has the highest boiling point?

    A) \[{{H}_{2}}\]

    B) \[Xe\]

    C)  \[C{{H}_{4}}\]

    D)  \[He\]

    Correct Answer: B

    Solution :

     Boiling point \[\propto \]vander Waals  force vander Waals force oc atomic mass (or molecular mass) \[\because \]Atomic mass of Xe is highest among.\[{{\text{H}}_{\text{2}}}\text{,He,}\,\text{C}{{\text{H}}_{\text{4}}}\text{,}\,\text{Xe}\] \[\therefore \] Boiling point of Xe is highest.
