Frequently Asked Questions:

Q1) Why are we not obtaining an 1H-NMR spectrum of our oxidized product?

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?

A2) See this explanation from the SN1/SN2 experiment page.
