Which one has the highest boiling point?

Solution
The correct option is D Xe
Xe
Down a group in the periodic table, due to a higher number of electrons in the molecules, there is greater distortion and hence higher frequency and magnitude of the temporary dipoles. Thus the Van der Waal's forces between the molecules are stronger and the melting and boiling points are greater down the group.
