hydrg bndng is the basis for all the props of h2o expt: exclnt solvnt/high boil pnt/viscsty/lack srfc tension?

Answer 1

Boy! Let me guess what you are asking:
Hydrogen bonding is the basis for all the properties of H2O except: excellent solvent /high boiling point /viscosity /lack of surface tension?
No, you are wrong. Hydrogen bonding is the basis for many properties of H2O, except, for example, some chemical reactivity.
1) excellent solvent is related to its hydrogen bonding capability, such that ionic compounds can be dissolved, but solubility of non-polar molecules is very poor.
2) high boiling point is due to strong inter-molecular interaction, in this case strong hydrogen bonding.
3) viscosity?
4) Definitely water has high surface tension, which is strongly related to its hydrogen bonding
