When to use sodium borohydride and when to use lithium aluminum hydride for reducing an aldehyde?
1. Compare the use of sodium borohydride versus lithium aluminum hydride in terms of handling and usage. 2. Be able to decide when to use sodium borohydride and when to use lithium aluminum hydride for reducing an aldehyde.
Sodium borohydride is preferred over lithium aluminum hydride as a reducing agent to convert carbonyl compounds to alcohols. State two reasons why.
Compare the use of sodium borohydride versus lithium aluminum hydride in terms of handling and usage.
2. Be able to decide when to use sodium borohydride and when to use lithium aluminum hydride for reducing an aldehyde. 3. If you reduce a compound containing an aldehyde, what qualitative test would you use to determine if the product is good or bad? 4. Draw the mechanism for the reduction of vanillin vanillyl alcohol.

Sodium borohydride is normally produced by the reaction of sodium hydride with trimethyl borate according to the following equation. NaH + B(OCH3)3 ® NaBH4 + NaOCH3 a) Balance the above equation. Be sure to get this correct since your answer to part (b) depends on your correct balancing of the equation. b) If 18.3 g of NaH are reacted with 18.5 g of B(OCH3)3, what is the maximum mass of NaBH4 that can be produced?
