In these problems you will be asked to draw the structures corresponding to compound names.
Tens of millions of organic compounds have already been studied, and the number of possible structures is infinite, so a very sophisticated system is needed for naming them. The most widely used system is that formulated by the International Union for Pure and Applied Chemistry, usually called the IUPAC system. Although software is increasingly used for chemical nomenclature, it is still important that chemists be able to understand IUPAC names.
1. Choose one or more families of compounds, and set the desired dfficulty level, using the controls on the left below, and then click the "Get Problem" button.
2. The problem will be shown above the molecule drawing window. Draw the structure in the window and click the "Check Structure" button. Feedback will be provided.
3. If the structure is not correct, study the feedback and consult the relevant Help pages if you wish, then modify the structure and and click on the "Check Structure" button again.
