A1) It turns out that a simple 1H-NMR spectrum is not particularly useful; it cannot be used to assign protons in a straightforward manner. The spectrum below was obtained from a student sample and demonstrates the difficulty of assigning spectra for this compound. Only the 9 H-atoms in the tert-butyl group are readily discernible. For this molecule, IR and GC-MS are more useful methods of simple analysis.
Q2) What is a drying agent? Why do we need them? What do they do?
