Hydrogen bond is a weak electrostatic force of attraction between covalently bonded hydrogen and more electronegative species like F,O and N. It play an important role in influencing many physical constants. It is a weaker bond than covalent bond but stronger than vanderWaal forces of attraction. Which of the following can exsist as a hexamer in vapour state ?
