Do you expect the reduction reaction of camphor using sodium borohydride to yield an equivalent amount of borneol isomers (borneol and isoborneol)? If not, predict which diastereomer would be the major product and show/explain why.

Reduction of Camphor Lab 1) Provide a mechanism that accounts for the formation of both Borneol and Isoborneol. 2) In lecture we have consistently discussed the fact when we add to a sp^2 hybridized carbon we normally see no facial preference. Use your mechanism to explain why more isoborneol is formed from the reduction reaction. How would you expect the product distribution to change if methyl groups are missing from the camphor structure.

In the experiment of the reduction of camphor to isoborneol, how is the percent yield calculated? 0.1038 g of camphor is initially used. 0.0447 g of NaBH4 is the reducing agent. 0.0524 g of product is obtained. Per the manual, stoichiometry is 4 moles of camphor to one mole of NaBH4 MW of camphor is 152.23 MW of isoborneol is 154.24 Please help explain. Thank you

EXPERIMENT SEVEN SODIUM BOROHYDRIDE REDUCTION OF ACETOPHENONE HOCH, DISCUSSION The reduction of an aldehyde or ketone with sodium borohydride is straight forward and usually affords a high yield of the alcohol. The usual procedure (and the one employed in this experiment) involves dissolving the borohydride in 95% ethanol and adding the carbonyl compound to this solution. To ensure complete reaction, an excess of sodium borohydride is used. The reaction between sodium...
