Organic Chemistry Lab: Reduction and Spectroscopy
1. Sketch the NMR spectrum you would expect to observe for the following compounds:
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?
