Chairs of cis-1,2-dimethylcyclohexane (a,e ⇌ e,a, equal energy) and trans-1,2-dimethylcyclohexane (e,e strongly favoured over a,a), with the wedge drawings and CIP labels. ## What the template shows - cis = both CH₃ on the same face (one axial, one equatorial); trans = opposite faces (both equatorial or both axial) - Ring flips of the two diastereomers - C1 axial, C2 equatorial - C1 equatorial, C2 axial - cis (1R,2S): meso - favours right - diaxial: four 1,3-diaxial clashes, minor - diequatorial: major (about 99 %) - trans (1S,2S): chiral - cis/trans is fixed by the bonds; axial/equatorial changes with the ring flip. A ring flip never turns cis into trans. - cis-1,2: axial/equatorial ⇌ equatorial/axial, two chairs of equal energy (they are mirror images; the compound is meso). - trans-1,2: the diequatorial chair (one gauche CH₃/CH₃, about 3.8 kJ mol⁻¹) is far more stable than the diaxial one (four 1,3-diaxial CH₃/H, about 15 kJ mol⁻¹). - So trans-1,2-dimethylcyclohexane is the more stable diastereomer, by about 7.5 kJ mol⁻¹. - Wedge = toward you, hash = away from you · every part of this figure is editable Drawn with 16 atoms, 43 shapes – every one editable in MolDraw. ## Sources - [Clayden, Greeves & Warren, Organic Chemistry, 2nd ed., OUP 2012, ch. 16](https://openlibrary.org/isbn/9780199270293) Textbook - [Eliel & Wilen, Stereochemistry of Organic Compounds, Wiley 1994, ch. 11](https://openlibrary.org/isbn/9780471016700) Textbook ## How to use this template 1. Press **Edit in MolDraw**. The template opens on the canvas of the free MolDraw editor. 2. Change anything: move structures, edit atoms and labels, recolour highlights or delete what you do not need. 3. Add your own structures, arrows and text next to it, or combine several templates on one page. 4. Export the drawing as PNG, SVG or PDF for slides, worksheets, theses and papers. ## Frequently asked questions ### Is the cis- and trans-1,2-Dimethylcyclohexane template free? You can preview the cis- and trans-1,2-Dimethylcyclohexane template here and open and edit it in MolDraw for free. Downloading or exporting it is part of MolDraw Pro, together with the other premium templates. ### Can I edit the cis- and trans-1,2-Dimethylcyclohexane template? Yes. It opens as an ordinary MolDraw drawing, so every structure, arrow, label and colour can be changed, and you can add your own content around it. ### Is the chemistry checked? Every structure is checked with RDKit and every curly arrow passes MolDraw’s electron-flow audit. The sources used are listed on this page. ### Are the R/S labels in the stereochemistry templates checked? Yes. Every R/S and E/Z descriptor is computed with RDKit from the drawn structure, so the labels match the wedges and dashes. ## More stereochemistry templates [**Assigning R and S**Free · Stereochemistry](https://www.moldraw.com/templates/stereo-rs-assignment/)[**Newman projections: butane**Free · Stereochemistry](https://www.moldraw.com/templates/stereo-newman-butane/)[**Cyclohexane chair and ring flip**Free · Stereochemistry](https://www.moldraw.com/templates/stereo-chair-ring-flip/)[**CIP priority rules**Premium · Stereochemistry](https://www.moldraw.com/templates/stereo-cip-rules/)[**E/Z and cis/trans alkenes**Premium · Stereochemistry](https://www.moldraw.com/templates/stereo-ez-alkenes/)[**Enantiomers and diastereomers**Premium · Stereochemistry](https://www.moldraw.com/templates/stereo-enantiomers-diastereomers/)[**Meso compounds: 2,3-dibromobutane**Premium · Stereochemistry](https://www.moldraw.com/templates/stereo-meso-dibromobutane/)[**Tartaric acid stereoisomers**Premium · Stereochemistry](https://www.moldraw.com/templates/stereo-tartaric-acid/) ## Related pages [**Chirality & R/S Configuration Worksheet**Free printable worksheet](https://www.moldraw.com/educational-materials/chirality-rs-worksheet/)[**Structural Isomers & Stereoisomers Worksheet**Free printable worksheet](https://www.moldraw.com/educational-materials/isomers-worksheet/)[**All Stereochemistry templates**17 templates](https://www.moldraw.com/templates/stereochemistry/)[**All chemistry templates**370 templates in 29 categories](https://www.moldraw.com/templates/) MolDraw Pro Download all 370 templates - Export the 291 premium templates as PNG, SVG or PDF - AI chemistry assistant - Structure scanning from images - Cloud save and teaching slides [See Pro plans](https://www.moldraw.com/pricing) Free templates stay free.
