IUPAC Nomenclature: Machines Do It Better Historically, the systematic naming of a compound was important in order to uniquely identify it and record relevant information about that compound. Today, computers are able to read and interpret graphical drawings of chemical structures; thus, the skill to name a compound no longer carries the importance that it once did. In the MarvinSketch example below, the program is being used to find the formal name of a tetrapropylene alkylbenzene sulfonate, a compound that once was used in laundry detergent. The IUPAC name is circled in the purple oval. Today, it is far more important that you have the ability to use these tools and interpret their results rather than be an aficionado of IUPAC nomenclature. http://www.chemaxon.com/anim/marvin/sketch_graphics/iupac.html

Abbreviated Groups Insert an abbreviated group into your sketch: type the name of the abbreviation, to complete a longer name, press ENTER or END after typing the first few characters. If the cursor was placed over an atom, it will be automatically changed to the abbreviated group. If no atom was selected,
