JEE Advanced Chemistry question

Hydrates of helium and neon have not been prepared because of

(A)Low polarisability
(B)Small size
(C)Low boiling point
(D)All of theseCorrect

Answer: (D)

Solution

Noble-gas clathrate hydrates (like Ar, Kr, Xe·nH2O) form when the gas atom is large and polarisable enough to be trapped by, and interact favourably (via induced dipole/van der Waals forces) with, the hydrogen-bonded water cage. He and Ne are too small to be effectively trapped
