How many signals would you expect in the 1H NMR spectrum of the following compound?

What happens when a compound absorbs IR radiation?

Consider the following problem.

Which of the following electromagnetic radiation is used in NMR spectroscopy?

A compound, with molecular formula C5H10Br2, displays the following 13C NMR along with the DEPT-90 and DEPT-135 13C NMR spectra. What is the structure for this compound?

There are 5 degrees of unsaturation in the compound found in this combined spectra problem. Briefly describe where each of those degrees of unsaturation come from. (What functional group, is it double bond, triple bond, rings. Be specific) You may need to scroll up to see the spectra.

Predict the pattern (multiplicity) of each signal in the expected 1H NMR spectrum of the following compound. Be as clear as you can (Ha = pattern, Hb = pattern etc. ) Do not write multiplet for a complex pattern. You should be able to report the complex pattern if necessary.

Which compound matches the spectra given in this combined spectra problem?

Which of the following is true about the shape (multiplicity or pattern) of the signal in a 1H NMR spectrum?  

For the following reaction that transforms a nitrile into an amide, explain how you will use IR spectroscopy to monitor the progress of the reaction.  (What signals would disappear and/or appear to let you know the reaction has been successful)
