INTEGRATED SPECTRA PROBLEMS

The following set of problems provide 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.

• You should attempt these problems in order (since the later ones tend to be more difficult).
• However, you can access a particular problem directly from the list below.
