Which one has the highest boiling point?

A

Kr

B

Xe

C

He

D

Ne

Text Solution

Verified by Experts

The correct Answer is:
B
As the size of the element increases down the group from He to Xe, the magnitude of the van der Walls forces of attraction also increase in the same way and hence the boiling points increase accordingly. Thus, Xe has the highest b.p.
