Which one has the highest boiling point?

A

`He`

B

`Ne`

C

`Kr`

D

`Xe`

Text Solution

Verified by Experts

The correct Answer is:
D
As we move down the group of noble gases, molecular mass increases by which dipole produced for a moment and hence London forces increases from `He` and `Xe`.
Therefore, more amounf of energy is required to break these forces, thus boiling point also increases from `He` and `Xe`.
