JEE Advanced Chemistry question

Thermal stability of hydrates of group 18 elements

(A)Increases down the groupCorrect
(B)Decreases down the group
(C)Remains unchanged
(D)First increases up to Ar and then decreases

Answer: (A)

Solution

Noble-gas clathrate hydrates are stabilised by van der Waals (induced-dipole) interactions between the trapped gas atom and the surrounding water cage, which strengthen as the noble-gas atom becomes larger and more polarisable down the group
