Sodium Borohydride Reduction of Benzoin Pre-Lab
Worksheet
(1) Why is it important to use 100% ethanol for this reaction? 5, ethanol (absolute ethanol) rather than 95% of benzoin? ow would you expect the IR spectrum of the reduced product to differ from that 7. (2) How would you expect the 1H rom that of benzNMR spectrum of the reduced product to differ 8. (2) How many peaks do you expect in the 13C NMR spectrum of the product? Suppose you...
Orgo Lab experiment: Isomerization of Carvone
1. Carvone contains a ketone and two double bonds. However, when
treated with the concentrated acid only one reacts to create the
carbocation. Which alkene reacts to form the carbocation and why
only the one?
2. After the carbocation rearranges an elimination occurs, the
alkene formed is a trisubstituted instead of the tetrasubstituted
alternative. Why is this odd and what is the driving force for this
specific alkene formation?
3. Using the H NMR...
Part A - Determination of number of H-NMR signals It is important to be able to recognize the significant spectroscopic differences among isomers and other compounds with a similar molecular structure Generally, analyzing the molecular structures and spectroscopic data to answer a few questions will help you identify how to distinguish among molecules with similar structures. The following questions are useful when using 1H-NMR to accomplish the goal: 1. How many spectroscopic signals are expected? 2. What are the expected...
Which compound gives the following spectra?
For the 1H-NMR assign all signals. interpret mol peak and base peak
in the mass spectrum if a mole peak exists. Assign at least two 13C
signals. How does the IR spectrum support your finding?
