Question

Pre-Lab Questions 1. What are some common solvents used in NMR sample preparation? 2. Are all molecules able to be analyzed using proton NMR? Explain. 3. Compare NMR radiation to x-ray radiation in terms of energy, wavelength, and frequency. 4. What do the terms upfield and downfield indicate on an NMR spectrum? 5. You overheard a classmate state that they did not want to run a sample in an NMR because the radiation would destroy their sample by 'breaking bonds'. Does your classmate have a valid point? Explain.

The Chemistry and Life box in Section 6.7 on pg. 237 of your textbook described the techniques called NMR and MRI. (2 pts) In your own words, what is NMR and what is MRI? (2 pts) Instruments for obtaining NMR data are typically labeled with a frequency, such as 400 MHz. In what region of the electromagnetic spectrum does a photon with this frequency belong? (3 pts) What is the value of ΔE that would correspond to the absorption of a photon of radiation with frequency 450 MHz? (2 pts) What is the wavelength (in nm) associated with a frequency of 450 MHz?

What is the purpose of NMR spectroscopy ? Question 1 options: It allows identification of functional groups present in the molecules. It provides the information about the number and types of bonds present within the molecules. It allows determination of carbon-hydrogen framework of a compound. It determines the composition of the compound. It allows determination of molecular mass and major pieces of the molecules.
