This experiment involves the use of a reducing agent (sodium borohydride) for converting a ketone (camphor) to a secondary alcohol (isoborneol) as illustrated in the second step of the two-step oxidation/reduction sequence shown below the spectra of borneol, camphor, and isoborneol will be. This is because when the sodium borohydride attacks the camphor, it would attack in the endo-phase due to the steric strain caused by the two geminal methyl groups on one side of the cyclohexane ring this can also be seen in the gas chromatography data in how the isoborneol peak is much larger than the borneol peak additionally from this spectroscopy, it can be seen that borneol. Oxidation of borneol (l(-))-borneol reacts with sodium hypochlorite with acetic acid to form (1s) camphor, hydronium ion, and chloride ion.

Oxidation of (1s)-(endo)-(-)-borneol suppose we had ran the oxidation reaction with racemic borneol is there an analytical technique we could use to verify that the camphor also is racemic what type ofinstrumentation would you use what kind of results would you expect for a racemic product mixture. Through an oxidation-reduction reaction sequence, borneol is converted to isoborneol first, borneol is oxidized through a reaction with sodium hypochlorite at 400c to form camphor when the camphor is then reduced by sodium borohydride, isoborneol is formed the percent yeild of isoborneol collected was 564%, and the melting point. Notes to the instructor we use commercial 6% sodium hypochlorite solution ( vwr scientific products, no vw3248-1) for this reaction because it more reliably oxidizes borneol to camphor even with this solution, however, some students may.
