Doc Brown's A-level chemistry: Associated advanced A-level organic chemistry pages

Using molecular spectroscopy to investigate and deduce the structure of an organic molecule

INDEX OF SPECTRA QUESTIONS - problem solving in organic chemistry

I have no objection to teachers or students doing a selective printout of these questions

I suggest teachers flip through the answers to pick out a suitable problem for the class.

You could also email students with the question link to solve in their own time.

You are given the infrared spectrum, mass spectrum, ¹H NMR spectrum and ¹³C NMR spectrum for an unknown molecule and one additional clue to help you deduce the identity and molecular structure of the molecule

Email doc b with any query or comment?
