Start Problems

Background:

This organic chemistry learning object allows you to work through a set of spectroscopy problems using an interactive drawing tool. After each attempt, your structure is assessed and you are given feedback to help you work towards the solution. Hints are available in many cases and worked solutions are provided.

The spectrocopy problems:

Each problem contains spectral data (mass spectrum, infra-red, 13C NMR and H NMR) for an unknown compound.
You are required to deduce the structure of the unknown compound that is consistent with all the data provided.
Some "general" hints are available to encourage you to look for the right information and to try to get you going. In addition, an online "tutor" will give you feedback on any wrong answers you submit. In general terms, the problems start easy and gradually get harder as you go, but similar or related problems are grouped together to help the learning process.

We are working on adding more problems when time allows....

Last problem update : As of June 7th 2018 there are 60 problems (22 easy, 22 medium, 14 difficult, 2 extreme).
