Question
In this experiment (part B), we aim to reduce camphor, obtained from Part A of the experiment, to isoborneol using sodium borohydride (NaBH4).
Part B:
4. When sodium borohydride is added to methanol, bubbling is often observed. Why?
5. Predict the most likely product formed from the reaction of optically pure
(+)-menthone with sodium borohydride.
(+)-menthone
6. Explain why the gem-dimethyl groups of camphor appear as two singlets in the NMR,
when normally gem-dimethyl groups give one peak (as in 1,1-dimethylcyclohexane, for
example).
