Textbook Question

Chapter 14.12, Problem 15P

Hydrogen bonding between the oxygen of dimethyl sulfoxide (DMSO) and the proton of an OH group is relatively strong. How could recording an NMR spectrum in DMSO instead of CDCl 3 be helpful in distinguishing between primary, secondary, and tertiary alcohols?

Compare the 13C NMR spectra of isoborneol and camphor. Explain which peaks can be used to determine whether the oxidation was successful. Propose a mechanism for this oxidation. To simplify the structures, use benzyl alcohol to draw the mechanism instead of isoborneol. Include the formation of any byproduct(s) in the mechanism.
