SPECTROSCOPY QUIZ WITH ANSWERS #4
1. Which of the following wavelengths of light is the high- 250
nanometers
est in energy?
- 250 nanometers
- 3 centimeters
- 450 nanometers
- 400 micrometers
2. True or False: light with a higher frequency will have a false
longer wavelength
3. Without doing a calculation, which of the bonds
below C=O would you expect to have the higher
stretching fre- quency?
- C=O
- C-O
4. Which of the molecules listed below is most 1-hexene
likely to give this IR spectrum?
5. What molecule is most likely represented by 3-hexanol
the IR spectrum shown her (attached)?
6. How many proton NMR signals will be observed for the 3
molecule: 3-methyl-2-butanone
7. What is the splitting pattern for the underlined protons quartet
in the molecule shown?: 3-pentanone (CH2)
8. Which of these esters would give the proton NMR spec- methyl
propionate
