What are the six properties of water that result from hydrogen bonding?

Jun 10, 2017

This is an old problem.........I don't think it is a particularly good one....

Explanation:

And the six properties:

$1.$ $\text{Surface tension}$; the surface tension of water is particularly high.

$2.$ $\text{Elevated specific heat capacity.}$

$3.$ $\text{Elevated specific heat of vaporization.}$

$4.$ $\text{Unusual density of liquid VERSUS solid water.}$ That ice floats on LIQUID water is a HIGHLY unusual property for a liquid. Normally the solid-phase would be DENSER than the liquid phase. The peculiar structure of liquid water at $4$ ""^@, which is a consequence of hydrogen bonding, gives rise to the density. That water is exceptionally dense, certainly denser than most organic solvents, also reflects this property.

$5.$ $\text{Elevated boiling point}$. The normal boiling point of water, which of course is $100$ ""^@C is RIDICULOUSLY high. You compare this with other small molecules, $N {H}_{3}$, $C {H}_{4}$, $N {O}_{2}$, $S {O}_{2}$ etc. and the boiling point of water is EXCEPTIONAL.

$6.$ $\text{Elevated melting point}$. The $\text{normal melting point}$ of water at ?? is again exceptional, and unusual.

$7.$ $\text{Properties as a solvent}$. Water is a protic, POLAR solvent, which can solvate MOST substances. The polarity of the water molecule, i.e. $\stackrel{\delta +}{H} - \stackrel{\delta -}{O} - H$, which solvates anions, and cations, is the basis of this property.

I included this property because perhaps the other categories overlap somewhat.

You happy with this? The properties do overlap as I said.....
