Question
The correct order of solubility in water for He, Ne, Ar, Kr, Xe. is
Options
A.He > Ne > Ar > Kr > Xe
B.Xe > Kr > Ar > Ne > He
C.Ne > Ar > Kr > He > Xe
D.Ar > Ne > He > Kr > Xe
Solution
As the molecular weight of noble gas atoms increases down the group its polarityincreases due to which van-der-waal′s force between them increases. Due to increased polar it y of heavier inert gas its solubility in water also increase. So, most soluble gas will be Xe and least soluble will be He. So correct order is Xe > Kr > Ar > Ne> He
