1. Sketch the NMR spectrum you would expect to observe for the following compounds:
A. Acetone
B. 1,1,2-tribromoethane

2.Which of the isomeric butanols (C4H10) be prepared by reduction of a ketone with sodium borohydride?

3. In trans-1,2-dibenzoylethylene, even though the conjugated C=O group frequency coincides directly with the expected C=C stretching fequency, we would not have expected to observe the late stretching mode in the infrared spectum. Why?

Solution Summary

The solution examines reduction and spectroscopy. The NMR spectrum is sketched for acetone and 1,1,2-tribromoethane.
