Disubstituted cyclohexanes?

Is it just me, or is this completely irrelevant to an article titled methyl cyclohexane? Tycarter —Preceding undated comment added 18:12, 25 May 2012 (UTC).

No, it is not you—this section is immaterial to the article, and I will move it here to talk (see next section). Le Prof Leprof 7272 (talk) 04:21, 23 May 2014 (UTC)

Moving non-germane paragraph and section to talk

The article is about a specific organic molecule that has a single methyl group attached to a cyclohexane ring. The "disubstituted cyclohexanes" section is appropriate for the cyclohexanes article, but entirely inappropriate here. It will be moved to talk, so that the text, if of value elsewhere, is saved for re-use. Le Prof Leprof 7272 (talk) 04:21, 23 May 2014 (UTC)

Here is the non-germane paragraph. Note, for the record, I am a trained PhD organic chemist. This is not vandalism, it is good science. This is misplaced pre A-level writing, and never should have been placed here to begin with. Note, also, no citation for the content is given. When it is placed elsewhere, editors at the new location should require sourcing. In my view, even rightly placed, this is not encyclopedic content. (Signed below.)

* Disubstituted cyclohexanes

Cyclohexanes could also have more than one methyl branch. Disubstituted cyclohexane, or also known as dimethylcyclohexane has two methyl branches. Unlike the monosubstituted cyclohexane, there are several possible structures. The methyl groups could be on the same carbon, separate carbons and it doesn't necessarily have to be on the same face. The 1,3-diaxial strain interactions still apply to the disubstituted. If the methyl groups are on different faces and both in axial positions, there are diaxial interactions with the axial hydrogen groups on both faces. If they are on the same face, both methyl groups interact with the one hydrogen that is in axial position and there is also a methyl-methyl interaction with a steric energy of approximately 15.3 kJ/mol. If the methyl groups are on adjacent carbons of the cyclohexane, with one of them axial and the other equatorial, there would be a gauche interaction which adds to the total strain energy the molecule has. For the dimethylcyclohexane which has two methyl groups on one carbon (1,1-dimethylcyclohexane), one methyl group is axial and the other equatorial. It would have the same total strain energy as the monosubstituted cyclohexane with axial methyl.

Article improved, but remains a citation-lacking, content-lacking stub

Please help to improve. Please do not add further material that is without good secondary sources, or that is off point with regard to the specific single molecule (methylcyclohexane) that is supposed to be the topic. Le Prof

Primary citation tag removed, overly focused primary referenced swapped out

 Done Review papers from AIAA, from leaders in field, substituted for overly focused primary reference. Article still needs attention from expert, because contains no real citations, so tag being added. Le Prof Leprof 7272 (talk) 17:10, 27 May 2014 (UTC)
