Organic molecules fascinate chemists due to the rich range of structures they can show: from methane (CH4) to DNA or bigger. One particularly interesting concept is the fact that some organic compounds can exist as pairs of non superimposable mirror images (for a visual image think of your own pair of hands). We are interested in  machine learning processes that are able to recognise chiral structures in large ensembles of molecules, especially when these are only presented in the 2D line drawn format that chemists have used for over 100 years. Suprisingly, there are relatively few well curated databases that contain this information, especially for the more unusual manifestations of chirality.  Your help in achieving this goal is massively appreciated.

Stereochemically Labelled Molecular Images

Chiral Molecules

For each initial image: (1) Decide if the molecule presented is chiral (or at least has the potential to be). (2) Work through the questions presented about the potential chiral elements presented (if present). If you wish you may use the text keys to provide an assignment (R, S, P, M, +, -, etc.) for the stereochemical features you choose, but this is optional. (3) If the molecule is achiral (i.e. not chiral) you will be given the opportunity to tell us why. (4) You can either end at this point, take another example.
