Then click on the 'Submit Answer' button. It may be slow loading the first time.) When you have finished the structure, click on the 'Insert Answer' button, and the applet inserts the unique smiles string into the text box. (You must have Java installed and enabled for the editor's applet to load. To answer a problem, click on the 'Draw Molecule' button, then a new window appears with the editor. When you think you have the hang of drawing the structures, then proceed to the homework problem. To begin, go the the University of Southern Maine's tutorial page for instruction on using this editor and for practice. (It is used because it can convert your structure into a unique 'string' that can be evaluated by the computer). LON-CAPA uses the JME Molecular Editor for the task of drawing structures in response to questions. A much better way is by using a computer program designed to draw the structure. An 'old fashioned' way would be to draw the structure by hand, scan it, and convert it to an image such as a gif file. As computers have become more important in this process, it becomes important to be able to represent these structures on the computer. Students learn how to represent structures in different ways (Lewis structure, condensed structure, line structure, and 3D structure) on the 2 dimensional page.
