[Edit in MolDraw](https://www.moldraw.com/)[Download SVG](https://www.moldraw.com/templates/download/library-isomerism.svg)

Free template. Download it, or open it in MolDraw to change it first.

Chain, position and functional-group isomers, cis/trans and E/Z, enantiomers and diastereomers with examples.

## What the template shows

- Same molecular formula, different structure: structural, geometric and optical isomers
- Structural isomers
- atoms joined in a different order
- C₂H₆O · functional group
- Dimethyl ether
- Geometric isomers
- no rotation about C=C
- cis-But-2-ene
- trans-But-2-ene
- Maleic acid
- (Z)-butenedioic acid
- Fumaric acid
- (E)-butenedioic acid
- Optical isomers
- enantiomers: non-superimposable mirror images
- (R)-Lactic acid
- (S)-Lactic acid
- stereoisomers that are not mirror images
- L-Tartaric acid
- meso-Tartaric acid
- A stereocentre is a carbon with four different groups; n stereocentres give at most 2ⁿ stereoisomers.
- Enantiomers rotate plane-polarised light equally in opposite directions; a meso compound has an internal mirror plane.

Drawn with 90 atoms, 4 shapes – every one editable in MolDraw.

## Frequently asked questions

### Is the Isomerism template free?

Yes. The Isomerism template is one of the free MolDraw templates: open it in the editor or download it from this page as SVG or PNG and use it in your slides, worksheets and notes.

### Can I edit the Isomerism 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.

### Which functional groups are included?

Alkanes, alkenes, alkynes, arenes, alcohols, ethers, aldehydes, ketones, carboxylic acids and their derivatives, amines, nitriles and more, each with an example.
