Talk:Structural formula

message: "A ring structure can be drawn in chair perspective." Huh? -- postglock 12:55, 20 September 2005 (UTC)
replies: text: I believe the editor was trying to refer to the different arrangements of cyclohexane, where the chair conformation is the lowest energy form. I've expanded the section a bit to cover the use of dots & wedges in all three-dimensional molecules. GeeJo (t) (c) 15:25, 6 December 2005 (UTC)

text: I think that the chair is a teaching point used to explain optical isomerism, when drawn in a certain way a molecule could be made to look like a chair and it's reverse a non-super imposable chair - see  for details. Philipwhiuk (talk) 14:26, 6 January 2008 (UTC)
thread_title:  Chair perspective 

message: Some articles like keytone and functional group follow the standard practice of using "R" (sometimes with subscripts) to represent arbitrary structures.  This practice should be explained in this article including why "R" is the symbol chosen and what it stands for.  (Radical (chemistry)?) I've added the same note to Talk:Chemical formula. -- Beland (talk) 16:15, 19 April 2008 (UTC)

message: Hey, the history is completely missing! Was is Edward Frankland in its Lecture Notes for Chemical Students (1866) who introduced the graphical notation (see the book at Google books)? -- Nichtich (talk) 15:12, 25 May 2008 (UTC)

message: The article says "Their structural formulae are shown at right:" - but I don't believe they are...
Diagrams are shown indicating the arrangement of atoms, but the actual structural formulae (to my understanding) are not shown. For instance, for isobutane, in the structural formula CH(CH_3)_3, indicating than the central sub-structure should be written first?
Sorry if this is a really silly point / question - I'm looking at this article for a reason :-)

thread_title:  Example? 

message: Br77rino added today a structure for fructose with a squiggly line which he said has an "unknown meaning", and added in the edit summary "trying to get an answer". In fact the two possible ring structures are called anomers and are in chemical equilibrium with each other and also with the open-chain structure. The ring continually opens and closes, and when it closes it sometimes closes in one stereochemistry and sometimes in the other. For more details see Fructose and Anomer.

thread_title:  page reorganization and elaboration 

message: Should there be a section about some of the limitations of the Structural Formula?  For example, differences in convention of representing dative bonds, aromaticity, tautomerism and other dynamic effects, atropisomers, salts, solvates, etc.  I believe that a nod to George Box's "all models are wrong..." would make the article more complete and informative.  — Preceding unsigned comment added by Bogtastic (talk • contribs) 16:51, 15 March 2018 (UTC)

message: I suggest we clarify that dashed and solid-vedge bonds are used to depict a spatial (a three-dimensional structure or) distribution of atoms in molecules. AXONOV (talk) ⚑ 17:16, 25 May 2022 (UTC)
