IR Spectral Interpretation Workshop, Quiz 2

This quiz is a regular feature of the “IR Spectral Interpretation Workshop” column. In each installment, we present a quiz. The answers appear in the subsequent installment. (For previous quiz questions and answers, click here.)

What we teach in each installment should help you answer the quiz questions. And there is a prize! One reader, selected at random from all who submit correct responses, will receive a signed copy of Brian Smith's book on IR spectral interpretation.

Good luck and happy interpreting!

Quiz 2:

The problem spectrum is shown in the figure below. Using the peak positions shown, do your best to assign all the peaks to determine the functional groups present. Then, put the functional groups together to come up with a proposed chemical structure.

Feel free to make use of reference spectra already published in previous "IR Spectral Interpretation Workshop" columns.


Figure: The IR spectrum of a liquid. Sampling method: capillary thin film.
