Which of the following inert gas is soluble in water?
He
Ne
Ar
Xe
D.
Xe
Solubility of inert gas in water is due to dipole induced dipole interaction. As the size of the inert gas increases, the extent of polarisation increases. Consequently, the magnitude of the dipole induced dipole interaction increases and hence, the solubility of the noble gas in water increases from He to Rn.
