a. Calculate the minimum amount (mmol and mg) of NaBH4 required to fully reduce your starting material given that it can reduce 4 equivalents of carbonyl functional groups. b. Calculate the minimum amount (mmol and mg) of NaBH4 required to fully reduce your starting material given that it can reduce 1 equivalent of carbonyl functional groups. c. Calculate the theoretical yield of each possible reduction product (mmol and mg) assuming NaBH4 can reduce 4 equivalents of carbonyls.
