Please remember that spelling and syntax are always 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 provided to help you work out where you went wrong.
If it is not obvious from the feedback why it is not correct, check the alphabetisation and the syntax (spaces, commas, hyphens etc.)
Note the syntax feedback is tricky to code for.
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.
