Post-lab Question #1: While both NaBH4 and LiAlH4 can both beused toreduce ketones and aldehydes, the procedure that youfollowed in lab wouldnot result in the fluorenol product if NaBH4were simply replaced with LiAlH4. a) Explain why. b) What change tothe procedure would have to be made to use LiAlH4 tosuccessfullyreduce fluorenone to fluorenol?
Post-lab Question #2: NaBH4 is not capable of reducing esterssince estersare less reactive than ketones. Explain structurallywhy this is the case.
Post-lab Question #3: In lab, NaBH4 was kept in a dessicator toavoidprolonged contact with water in the atmosphere. This is donesince waterwill react with NaBH4. Write the balanced equation forthe decomposition of NaBH4 by water.
Post-lab Question #4: It is found that a bottle of NaBH4 in alab contains 70% NaBH4 by mass as a significant portion has reactedwith atmosphericwater as described in question 3 above. What is theminimum that astudent should weigh out to fully reduce 3.18 g offluorenone?
