Interactive Spectroscopy 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. The problems start easy and get harder as you go.

We are working on adding more problems.

Last problem update : As of June 1st 2022 there are 60 problems (23 easy, 21 medium, 14 difficult, 2 extreme).

• Use the buttons to show the spectra
• Draw your answer in the window in the left and submit it.
• Review the feedback in the middle column.
• Hints are available after you have made 3 attempts.
  
• A worked solution is available after 8 attempts.
• The score per question is given when you get the answer, it is based on the number of attempts and how many hints you use. When you exit, you will be given your overall total.
  
• The difficulty level is indicated on the downhill skiing scale...
