Indeed there isn't. It isn't a discussion either--you asked a question, which I answered, while you continued to argue from ignorance.



1. You still haven't answered why other more authorative sites such as ChemSpider also display ball-and-stick as per the later Wiki version. (If more than one authorative site does so then there must be some reason for it - for this common consistency.)

2. You have failed to realize the significance of being consistent in presentation especially when stuff is presented in encyclopedic form. To do so in any other way is misleading.

That means that the skeletal and ball-and-stick depictions should be consistent with each other (otherwise it's confusingly - except for geniuses such as yourself of course).

Can't you understand that many people compare both models and that they expect them to match? (It's common practice to count the hydrogens on both to cross reference the chemical formula, etc., etc. - that's a common teaching practice where I come from.)

3. I never said that I disagreed with your assessment of the chemistry and I still don't. In fact, I do understand what you are talking about but (a) it's irrelevant if I do or don't in this instance and (b) expressing the more 'complex' state of molecules isn't normal practice in encyclopedic references. Yes, I'd agree that in textbooks such detail is normal but not here.

If you want to be precise to the nth degree and grind things superfine AND also be consistent across chemistry (i.e.: have common and consistant [standard] nomenclature to describe things) then you could not describe water as just 'H2O'.

OK: now where do we start for a proper formulaic description of water?

We would have to add in hydronium - or should that be hydroxonium (I learned the latter but I'm happy with both). Or should we refer to that as 'oxonium' only? Or should we start the description with something as confusing as:

Water = H20+H3O+ +... . ('water' + oxonium-type ion and then some extras)

How do we describe the protonation in its fullest form (as a formula)?

As you ought to know, this gets even more complicated, should we add in all known cations (Zundel, etc.) for a basic description of water just to ensure the formula is complete in all circumstances (cover all states/conditions)? (And then add a footnote that we may still not have them all as others may still be there - yet to be discovered).

Of course not. It's ridiculous.

Any chemist who works at that level already knows this stuff so it's unnecessary to describe the 'basic' molecule - dare I say it - in anything other than in its simplest (basic) form.

I do not owe you any answer, let alone why someone who is not me decides to represent anything in any form. Both versions (the original ball-and-stick model and the current skeletal structure) are valid, though one of them accounts for protolysis, and one doesn't.

  >2. You have failed to realize the significance of being consistent in presentation especially when stuff is presented in encyclopedic form.
My point was not that the current version is or isn't consistent, my point was that it is WRONG.

  >except for geniuses such as yourself of course
Next to you, I would appear that way. Go to the current version (https://en.wikipedia.org/wiki/Aspartame#/media/File:Aspartam...) and count the hydrogen atoms. Then compare to the actual molecular formula of aspartame.

I'll accept an apology, but please stop being this obtuse.


Armistice and olive branch. :-)

I accept your point. As I said earlier, I'm not arguing the chemistry, it's just the issues aren't the same (from my perspective anyway).


I'll take it :-)
