  • In this educational video, Sanziana Foia introduces us to optical isomerism and chirality. To help us learn about it, Sanziana starts from everyday objects, like hands and screws, and then moves on to molecules. In this short organic chemistry tutorial, we will learn what optical isomers and chiral molecule are, why chirality is important, and see examples, such as carvone. A fun quiz with more examples will conclude the tutorial. The molecules used to demonstrate these concepts are available in the Cambridge Structural Database (CSD). In particular we used CSD Entries: OGUSIV, RERXIV, KOSNIS, LALNIN03, CITRAC10, JEKNOC10, THALID03. You can visualise and download the structures for free from CCDC's Access Structures service: The images and animation frames of these molecules are prepared using Mercury. Mercury visualisation software is available to download for free More advanced functionality from the CCDC enables you explore molecules and structures in more detail, for example Molecule Overlay, which you could use to superimpose chiral molecules. To find out how to access more advanced functionality with a CSD-Core license see For educators and teachers: Feel free to show this video tutorial about optical isomerism, enantiomers and chirality in your classroom or you can get in touch with us to request specific animations.
