Which among the following has the highest volatility ?

Boiling point α 1VolatilityB.Pt order : H2S < H2Se < H2Te < H2OBoiling point orderFrom →H2S to H2Te As the size of central atom increases,size of molecule [or MWT] increases , and hence intermolecular attractions between the molecules increases.Inorder to break up those attractions we need to provide more amount of energy in the form of B.Pt [heat]H2O possess exceptionally hight B.Pt among all the VIA group hybrides, due to its ability to form intermolecular hydrogen bonding∴ The volatility order is →H2S > H2Se >H2Te >H2OAs the B.Pt increases, volatility decreases.Note :- Volatility is the property of a compound, how  easily it undergoes vapourisation.
