Maybe I am missing something, but Wikipedia seems to have no or few categories relevant to nitration or related reactions. Or perhaps the categories favor compound types vs reaction types. -- Smokefoot ( talk) 16:06, 17 August 2016 (UTC)
For a number of days the article Christopher J. Schofield is hanging around on the list "Articles With Multiple Dablinks". I have taken a look at it, but it is too much for me. Can somebody take a look at the article and solve the 5 links to disambiguation pages?

To enter a chemical formula in Infoboxes {{
Chembox}} and {{
Infobox drug}}, they have the option to use | C=20 | H=21 | etc.
. (using {{
Chem}} and straight HTML-text is possible too). An editor
Aethyta asks that the parameter |D=
(Deuterium, or 2H) be added, to make possible C11H15D2NO3 (
Beta-D) to be entered that way. (Additional advantage is that the molecular mass can be calculated from these individual entries).
We could add "D" as an element symbol. I'd like to learn if there are any pitfalls or errors when doing so. - DePiep ( talk) 14:03, 27 June 2016 (UTC)
|D=
should be allowed just fine. No other element appears to have that same
symbol, so there shouldn't be any complications. The very few deuterium containing compounds with articles on Wikipedia included "D" in their formulae for many years, the only difference this change would cause is making it possible to be used via the shortened input form that also calculates the molar mass.

Hi. An editor was going through chemical articles adding ELs to the MSDS and tech specs from a single company and I reverted them as spamming. They left a note on my talk page saying they were looking to do this across many many more chemical articles, and I referred them here. They found some old discussions; I looked too, and it isn't clear to me what you all are doing now. The user seems to have chickened out from asking you all, so here I am. I run into some of this on drug articles I work on.
I looked at Sodium chloride and its associated Sodium chloride (data page) and MOS:CHEM as well as WP:MOSCHEM/SAFE (and i just now saw the discussion of MSDS at the bottom of that page, here and i totally get what it says there - it was one thing bothering me about the edits I reverted)
MOSCHEM doesn't mention "data page" at all; is creating these still your current practice?
It seems that for each article, you fill out the Template:Chembox and fill out the associated data page (?) but it is not clear to me where that data is actually coming from... sources aren't cited for everything. Are you actually using MSDS' for that data?
I can kind of understand where that editor was coming from, as sources for data in the chembox aren't clear to me. Where is it coming from?

Hello, I have a small problem with a chemical, octopamine: en:WP is the only Wikipedia which does the difference between the drug ( Octopamine (drug)) and the neurotransmitter ( Octopamine (neurotransmitter)), all three articles having their own item in WD. This is your choice. But for WD this splitting is a problem because we don't want to do the differences between the possible uses: this is a chemical so all data regarding this chemical should be located at the same place.
Is it a problem if I merge all data in the item linked to octopamine and recycle the 2 other items for R- and S-octopamine ? The consequence of this action is the lost of items dedicated for the drug and for the neurotransmitter with the possibility to link to articles in other Wikipedias (but currently only WP:en is doing the distinction). Snipre ( talk) 09:56, 10 October 2016 (UTC)
{{
main article}}
link to
octopamine (drug) in that section. IIRC the main reason for creating separate articles in both of these cases was to address a dispute about the use of {{
infobox neurotransmitter}}
vs {{
infobox drug}}
as the article's infobox.

The international standard nomenclature is sulfur, and -f- for all usages (established over twenty years ago). So it makes no sense that many pages still link to Sulphur and Sulphuric acid, and there is no good reason to (see editorial in Nature Chemistry.

Dear chemistry experts:
I came across this article which had been tagged for improvement. I have edited it extensively to make it more readable, add independent references, and to remove some opinion and peripheral material. However, I am not a chemist, so I am unable to deal with the section on the chemical reactions.

Just to announce you than thanks to the work of @ Sebotic:, Wikidata increases its coverage of chemicals with a total of ~98'000 chemicals having an item. All data were imported from PubChem and ChEBI and respect the rules about sources leading to a high improvement of the data quality. Right now an important step has to start to curate the data especially to merge duplicated items. You are welcome to take part to this action and you can get in touch with the Chemistry project in WD for details.
From that work additional importations can start in order to add more identifiers but please announce your intention of data import before any huge importation in order to coordinate the work of bots and of contributors curating the conflicts. Snipre ( talk) 10:10, 12 October 2016 (UTC)

Hi. Sorry to trouble the WikiProject over something so minor, but there's a self-published booked cited in Alcohol#Physical and chemical properties near the end of the section. It's written by Nicolae Sfetcu, who self-published his book through Lulu.com. Normally, I'd look for a better citation myself, but I'm terrible at chemistry, and I doubt I'd be competent to rewrite any part of the sourced content that was incorrect. If someone who knows what they're talking about could take a look (and hopefully replace the self-published book with something better), I'd really appreciate it. Thanks.

Parameter 1 | AA | AA | AA | - |
Parameter 2 | BB | - | BB | BB |
Parameter 3 | CC | DD | CC | FF |
Parameter 4 | EE | EE | - | GG |

For Dataset from DB2 we have a medium confidence compared to Dataset from DB1 and for Dataset from DB4 a low confidence. Snipre ( talk) 11:11, 27 January 2017 (UTC)
As a high school chemistry teacher, I know many students jump to Wikipedia for answers and examples of various concepts. I took a look at the single replacement reaction page, and noticed many errors. Formulas such as ZnCl (Zn has a +2 charge, not a +1), hydrogen written as H, not H2, down arrows on gases evoloved like hydrogen (which is used to denote precipitates, whereas up arrows denote gases produced), and erroneous reactions such as Na + BrCl3 --> NaCl + Br. I am well aware that this is volunteer driven to correct and update the pages, so I will do my best to correct errors as I find them (hoping editing subscripts and superscripts are intuitive). I would ask others to make a concerted effort to look at the basic chemistry pages to make sure that material is correct since so many students use them as a go to source for information. 108.217.142.106 ( talk) 04:21, 3 February 2017 (UTC)

Several members of the International Steering Committee of the Symposia on the Jahn-Teller effect have made large edits to (surprise!) Jahn-Teller effect. The additions are well written and well referenced but expansive and highly technical. So technical in fact that the effects that I've always associated with JT-effect like high-spin low-spin distortions simply aren't discussed. These changes were also made as one massive edit (+43,242). It would seem a shame to remove expert understanding from the article but I think we may need to reinstate parts of the original page to make it more accessible... maybe under some sort of 'overview' heading? There is a discussion at the talk page. -- Project Osprey ( talk) 23:02, 16 December 2016 (UTC)
I recently wrote an article on pyrithione which exists as a pair of tautomers (at right). Based on this source published by the University of Barcelona, I put pKa values of "−1.95 and +4.6 (thiol proton)" in the article. I can find sources supporting the 4.6 value, but not for the −1.95 value. Petergans has challenged it on the article talk page, but he cannot access the book source on google (I can view it from Australia, so access depends on the location of your IP address). The reference the book provides supporting the claim is no. 40, which should appear on page 356, here, but I cannot see that page to look to the source's source. My initial interpretation was the two values are for the two tautomers, as it seems reasonable to me that the thiol tautomer would be a weaker acid than the thione, and the greater ionisation of the thione would account for it being the major tautomeric form (despite the aromaticity of the thiol). However, the difference in values is very large and Petergans is correct that −1.95 is into the strong acid range. Can anyone explain why there are two values, as the quoted source suggests? Alternatively, should we remove the second value and just list +4.6. If so, should we make some note / comment about it? Thanks to all. :) EdChem ( talk) 00:23, 19 January 2017 (UTC)

To enter a chemical formula in Infoboxes {{
Chembox}} and {{
Infobox drug}}, they have the option to use | C=20 | H=21 | etc.
. (using {{
Chem}} and straight HTML-text is possible too). An editor
Aethyta asks that the parameter |D=
(Deuterium, or 2H) be added, to make possible C11H15D2NO3 (
Beta-D) to be entered that way. (Additional advantage is that the molecular mass can be calculated from these individual entries).
We could add "D" as an element symbol. I'd like to learn if there are any pitfalls or errors when doing so. - DePiep ( talk) 14:03, 27 June 2016 (UTC)
|D=
should be allowed just fine. No other element appears to have that same
symbol, so there shouldn't be any complications. The very few deuterium containing compounds with articles on Wikipedia included "D" in their formulae for many years, the only difference this change would cause is making it possible to be used via the shortened input form that also calculates the molar mass.

Hi. An editor was going through chemical articles adding ELs to the MSDS and tech specs from a single company and I reverted them as spamming. They left a note on my talk page saying they were looking to do this across many many more chemical articles, and I referred them here. They found some old discussions; I looked too, and it isn't clear to me what you all are doing now. The user seems to have chickened out from asking you all, so here I am. I run into some of this on drug articles I work on.
I looked at Sodium chloride and its associated Sodium chloride (data page) and MOS:CHEM as well as WP:MOSCHEM/SAFE (and i just now saw the discussion of MSDS at the bottom of that page, here and i totally get what it says there - it was one thing bothering me about the edits I reverted)
MOSCHEM doesn't mention "data page" at all; is creating these still your current practice?
It seems that for each article, you fill out the Template:Chembox and fill out the associated data page (?) but it is not clear to me where that data is actually coming from... sources aren't cited for everything. Are you actually using MSDS' for that data?
I can kind of understand where that editor was coming from, as sources for data in the chembox aren't clear to me. Where is it coming from?

Hello, I have a small problem with a chemical, octopamine: en:WP is the only Wikipedia which does the difference between the drug ( Octopamine (drug)) and the neurotransmitter ( Octopamine (neurotransmitter)), all three articles having their own item in WD. This is your choice. But for WD this splitting is a problem because we don't want to do the differences between the possible uses: this is a chemical so all data regarding this chemical should be located at the same place.
Is it a problem if I merge all data in the item linked to octopamine and recycle the 2 other items for R- and S-octopamine ? The consequence of this action is the lost of items dedicated for the drug and for the neurotransmitter with the possibility to link to articles in other Wikipedias (but currently only WP:en is doing the distinction).

{{

octopamine (drug) in that section. IIRC the main reason for creating separate articles in both of these cases was to address a dispute about the use of {{
infobox neurotransmitter}}
vs {{

Just to announce you than thanks to the work of @ Sebotic:, Wikidata increases its coverage of chemicals with a total of ~98'000 chemicals having an item. All data were imported from PubChem and ChEBI and respect the rules about sources leading to a high improvement of the data quality. Right now an important step has to start to curate the data especially to merge duplicated items. You are welcome to take part to this action and you can get in touch with the Chemistry project in WD for details.
From that work additional importations can start in order to add more identifiers but please announce your intention of data import before any huge importation in order to coordinate the work of bots and of contributors curating the conflicts. Snipre ( talk) 10:10, 12 October 2016 (UTC)

Hi. Sorry to trouble the WikiProject over something so minor, but there's a self-published booked cited in Alcohol#Physical and chemical properties near the end of the section. It's written by Nicolae Sfetcu, who self-published his book through Lulu.com. Normally, I'd look for a better citation myself, but I'm terrible at chemistry, and I doubt I'd be competent to rewrite any part of the sourced content that was incorrect. If someone who knows what they're talking about could take a look (and hopefully replace the self-published book with something better), I'd really appreciate it. Thanks.

As a high school chemistry teacher, I know many students jump to Wikipedia for answers and examples of various concepts. I took a look at the single replacement reaction page, and noticed many errors. Formulas such as ZnCl (Zn has a +2 charge, not a +1), hydrogen written as H, not H2, down arrows on gases evoloved like hydrogen (which is used to denote precipitates, whereas up arrows denote gases produced), and erroneous reactions such as Na + BrCl3 --> NaCl + Br. I am well aware that this is volunteer driven to correct and update the pages, so I will do my best to correct errors as I find them (hoping editing subscripts and superscripts are intuitive). I would ask others to make a concerted effort to look at the basic chemistry pages to make sure that material is correct since so many students use them as a go to source for information. 108.217.142.106 ( talk) 04:21, 3 February 2017 (UTC)

Several members of the International Steering Committee of the Symposia on the Jahn-Teller effect have made large edits to (surprise!) Jahn-Teller effect. The additions are well written and well referenced but expansive and highly technical. So technical in fact that the effects that I've always associated with JT-effect like high-spin low-spin distortions simply aren't discussed. These changes were also made as one massive edit (+43,242). It would seem a shame to remove expert understanding from the article but I think we may need to reinstate parts of the original page to make it more accessible... maybe under some sort of 'overview' heading?

I recently wrote an article on pyrithione which exists as a pair of tautomers (at right). Based on this source published by the University of Barcelona, I put pKa values of "−1.95 and +4.6 (thiol proton)" in the article. I can find sources supporting the 4.6 value, but not for the −1.95 value. Petergans has challenged it on the article talk page, but he cannot access the book source on google (I can view it from Australia, so access depends on the location of your IP address). The reference the book provides supporting the claim is no. 40, which should appear on page 356, here, but I cannot see that page to look to the source's source. My initial interpretation was the two values are for the two tautomers, as it seems reasonable to me that the thiol tautomer would be a weaker acid than the thione, and the greater ionisation of the thione would account for it being the major tautomeric form (despite the aromaticity of the thiol). However, the difference in values is very large and Petergans is correct that −1.95 is into the strong acid range. Can anyone explain why there are two values, as the quoted source suggests? Alternatively, should we remove the second value and just list +4.6. If so, should we make some note / comment about it? Thanks to all. :) EdChem ( talk) 00:23, 19 January 2017 (UTC)
