I am an A-level student going into university and I am looking for a source of organic synthesis problems and answers that is freely available on the internet. The difficulty level I am looking for is something like first year undergraduate level. Any links would be greatly appreciated.

  • $\begingroup$ I believe there is some site where you can practice synthesizing a compound (theoretically of course) by selecting reactants and starting materials. Very nice idea, but unfortunately I cannot find it anymore... anyone? $\endgroup$ – Jori Dec 11 '14 at 19:10

Search for the latest IChO tests and preparatory problems. You can find quite a few interesting problems.

Here are some tests: http://www.iuventa.sk/files/documents/5_icho/past%20competition%20tasks/volume3-icho41-45.pdf

http://icho2013.chem.msu.ru/materials/Preparatory_problems_IChO_2013.pdf (problems 18-21)

http://icho2014.hus.edu.vn/Preparatory-Problems/0001/01/Preparatory-Problems-224.html (problems 18-26)


Janice G. Smith's textbook "Organic Chemistry", while unfortunately expensive, has a good interactive workbook online which is useful even without the companion text.

You can find it here.

  • $\begingroup$ That website is not working for me. Does it work for anyone else? $\endgroup$ – yolo123 Dec 11 '14 at 22:38
  • $\begingroup$ @yolo123 Select the chapter, then open the corresponding multiple choice quiz. $\endgroup$ – Klaus-Dieter Warzecha Jan 7 '15 at 21:29
