Chemicals can have different common names in different countries (even in different labs in the same country). To avoid confusion, IUPAC (the International Union of Pure and Applied Chemistry), which celebrates its centenary in 2019, provides a set of standards that allow chemists all over the world to communicate clearly with each other.
The systematic naming of compounds can be regarded as a logic puzzle. Here are the IUPAC names of some of the compounds shown in the ‘Valuable vanilla’ article (pp. 24–28). Assign the common name (as used in the article) to each of these compounds (answers on p. 31).
