File:Acido dodecilbenzensolfonico 2.png[edit]

Missing either an H (to be "sulfonic acid" per filename) or an anionic charge (and renamed to be "sulfonate" conjugate base) on the single-bonded oxygen. Have File:Acido dodecilbenzensolfonico 1.png as alt. The cited "pubchem" source often makes this sort of mistake:( DMacks (talk) 03:49, 20 May 2019 (UTC)

File:Baekeland-1.svg[edit]

Structural mistake: the second reactant should be formaldehyde not acetone. File:Phenolharz0-1.svg is a viable alternative DMacks (talk) 03:33, 20 May 2019 (UTC)

File:Cis-crotonaldehyde structure.svg[edit]

Unused, low quality chemical structure; strange gaps between the kinks of the carbon chain. Have File:Structural formula of cis-crotonaldehyde.svg as high-quality replacement. Chem Sim 2001 (talk) 14:49, 17 May 2019 (UTC)

File:Jones Oxidation eines sekundären Alkohol zu einem Keton.svg[edit]

Broken, opaque & invalid SVG file (conversion error) with 49 sourcetext errors; also incorrect positioning of text and structures. Have File:Jones sek Richtig.svg as proper, high-quality replacement by the same author. Chem Sim 2001 (talk) 18:54, 10 May 2019 (UTC)

  • Symbol delete vote.svg Delete per nom. The mispositioned H on the upper- and lower-right structures are factual mistakes also. DMacks (talk) 14:26, 16 May 2019 (UTC)

Deleted: per nomination. --Christian Ferrer (talk) 17:06, 17 May 2019 (UTC)

Categories for discussion[edit]

Category:Methylene groups[edit]

Category for methylene groups containing a subcategory for methylene group (methanediyl group) and for files that are not methylene groups. Imo it's incorrect, according to IUPAC rules there is only one methylene group (and there is a category for this group already) and I don't know what else can be added to this cat. Wostr (talk) 23:11, 16 November 2018 (UTC) PS Probably Category:Methanediyl group should be renamed to Category:Methylene group and Category:Methylene groups may be switched to redirect. Wostr (talk) 23:13, 16 November 2018 (UTC)

@Grasso Luigi: As the creator of the category it would be good to hear your opinion on the suggestions above. --Leyo 11:21, 3 December 2018 (UTC)

File:3DAmmonium mandelate.png[edit]

Incorrect structure/geometry at ammonium. Leyo 00:13, 17 December 2015 (UTC)

  • This looks to have been changed. Though I would like to see the anion drawn more like what you see in File:Ammonium-acetate-3D-balls.png with a dotted line across the two oxygens. Graeme Bartlett (talk) 07:09, 19 December 2015 (UTC)
