Text Solution

Verified by Experts

(A)Argon
(B)Helium, Exists as mono-atomic molecules and are held together by weak van der Waal's forces.These van der Waal's forces increase with the increase in atomic size of the atom, and therefore, the boiling points increases from He to Rn.Hence He has least boiling point.
