In the default "Problem" mode, you can test yourself by drawing the structure of the molecule directly into the molecular editor window, some feedback will be provided, and your score will be updated. How To Use This Page: First, choose the family of compounds you want to work on, choose an "Easy", "Medium" or "Difficult" problem. Note that 3 points are deducted for each incorrect answer, and your score will be reset to zero if you reload the page. Set your own goals to suit your learning needs, but one measure of completing the section would be to achieve a score (below right, in green) of at least 40 points from 50 for five "Difficult" problems from the "All functional groups" category. On this page you can learn about the nomenclature of organic compounds by drawing structures corresponding to IUPAC names. Although software is increasingly used both to assign names to structures and to derive structures from names, it is still important that chemists be able to understand IUPAC names. The most widely used system of nomenclature is that formulated by the International Union for Pure and Applied Chemistry, usually called the IUPAC system. On completing these problems you should be able to:ĭraw the structures of moderately complex organic molecules from the IUPAC name.ĭemonstrate an understanding of the principles of organic nomenclature.īecause the number of known organic structures runs to many millions, and the number of possible structures is infinite, a sophisticated nomenclature system that is capable of naming structures unambiguously is needed. These exercises have been used for first year students at Faculty of Pharmacy, Lac Hong university, Vietnam.Nomenclature of Organic Compounds Learning Outcomes The three types of exercise were created: (i) students are given structure of an organic compound, then they have to identify a specific functional group inside this structure (ii) students are given the IUPAC name of an organic compound, then they have to draw structure of this compound (iii) students are given structures of an organic compound, then they have to write the IUPAC name of this compound. We have developed interactive web-based organic nomenclature exercises by integrating JSME Molecular Editor into the website.
We found that JSME Molecular Editor was a free and easy-to-use computer program for creating chemistry online course.
To create an organic chemistry course online, we need a tool that can draw chemical structure and can be embedded into the web. However, the number of free organic chemistry courses is limited. There has been an impressive growth of open online course in recent years.
