Basic IUPAC Organic Nomenclature

THIS PROGRAM USES JAVA FOR THE QUESTIONS & INTERACTIVE IMAGES

THEREFORE YOU MUST HAVE A RECENT VERSION OF JAVA (1.5.0_04 or newer) INSTALLED

There are slight differences between the browsers. It seems to work best in Internet Explorer, but it also works in Netscape / Mozilla / Firefox.

The score and the question count are tracked using cookies. If you have security restriction on cookies in your browser, then you may not get a score at the end but the program itself should still work.

In the following set of drills you need to provide the systematic IUPAC name for the compound whose line drawing (skeletal structure) is given.

Spelling and syntax are important

They are fundamental to nomenclature and so it is required in order to get the answer correct.

The problems in each section genearlly start easy and get more difficult (easiest = green - blue - black - double black = hardest)
When you think you know the answer to a question, enter the name in the text box provided.
Use lower case text when entering the names - it is case specific
Only use UPPER CASE for special terms such as E/Z or R/S stereochemistry and locants such as N.
To check the answer press "submit answer" (in IE "enter" also works).
Your answer and appropriate feedback messages will be displayed in the top box on the right of the page.
Previous answers and messages will be shifted down a position.
The automated feedback is to help you work out where you went wrong.
If it is not obvious from the feedback why it's not correct check the alphabetisation and the syntax (spaces, commas, hyphens etc.)
Note the syntax feedback may not always work correctly, we are working on improving that feature, treat it with caution for now.
If you get an answer correct, you will be able to move on to the next question.
If after 10 tries you haven't answered the question correctly, the solution will become available.
