Expert Answer:
- The oxygen has high electronegativity.
- Hence the O-H bond in H2O forms strong intermolecular hydrogen bonds.
- As a result, water exist as an associated molecule.
- But the other hydrides of group 16 do not form hydrogen bonds.
- Therefore they exist as discrete molecules.
- Thus, water shows unusual physical properties such as high thermal stability, high b.p., weaker acidic character as compared to the other hydrides of group 16.
