OK. Since I am fortunate enough to know something about this I tried to answer all issues. If I have misrepresented your thoughts I apologize.

I certainly don't mind being corrected, as if I did it would be hard to learn new things and it would greatly detract from the enjoyment of grad students when they get they chance to correct professors. I do mind being told I am incorrect when our two statements were pretty much identical.

Generally the high boiling point of water and its high heat capacity is due to the hydrogen bonding between molecules. However, Tango, you are correct that the addition of antifreeze increases the boiling point of water. This is due to the colligative properties of mixtures and the fact that anti-freeze has a higher vapor pressure than water. The addition of anti-freeze increases the overall boiling point, despite reducing the hydrogen bonding of the water molecules.

Hydrogen bonding is the major component of water's large heat capacity but does not explain the variation in boiling point (or freezing point) with the addition of anti-freeze

It is always possible to agree with someone without saying they are incorrect. The more the merrier, I hope to have half the knowledge about MBs as the people here do.

OK. An inaccurate explanation was offered. Sure did not seem to be a joke. I corrected it. My explanation allows someone to build upon it for greater knowledge in the future if they wish. Most other explanations that have been offered here will limit the ability to expand one's knowledge. Use the information as you choose.

Actually, the explanation was not inaccurate, perhaps not fully explained with bond stretch and electron density clouds, but more accurate than yours stating that inter-molecular forces have no affect on bond length. The use of either of those statements as a basis for expanding ones knowledge is probably best evaluated by an individual on their own.
