Does NaBH4 reduce aldehydes, esters, or both?
One molecule of NaBH4 can in theory reduce four ketone functional groups. If you had 25 mg of NaBH4, how many many mg of benzil could be fully reduced?
can you reduce imines using NaBH4?
1. Explain why one molecule of NaBH4 will reduce only two molecules of benzil. 2. In the case of reducing benzil, how many stereo centers will be produced?

Sodium borohydride (NaBH4) is used industrially in many organic syntheses. One way to prepare it is by reacting sodium hydride with gaseous diborane (B2H6). Assuming an 75.1% yield, how many grams of NaBH4 can be prepared by reacting 7.43 g of sodium hydride and 8.16 g of diborane? g
How many grams of C3H6O is required to deliver 2.4 moles?
For this rxn: 1-hexene, I2, THF, NaBH4 -> 1-hexanol How does the reaction and the equilibrium of the I2-THF-NaBH4 reaction influence it's reactivity towards a terminal alkene
please keep simple for the rxn 1-pentene 12-THF-NaBH4-Peroxides -> 1-pentanol How does the reaction and the equilibrium of the 12- THF-NaBH4 reaction influence it's reactivity towards a terminal alkene
