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.
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. Oxidation of an Aldehyde (Vanillin III) 5. Be able to determine the oxidation of carbon in different molecules. 6. Write the mechanism for this...
Consider lithium aluminum hydride (LAH), a reducing agent similar to NaBH, shown below. Would you expect LAH or NaBH, to be a stronger (more nucleophilic) reducing agent? Justify your answer. Consider the source of the nucleophilicity as discussed in the recorded lecture

What would be the products if a triglyceride was treated with a lithium aluminum hydride? Would it make a good detergent?
1. Write a mechanism for the reduction of vanillin using sodium borohydride. 2. Compare and contrast sodium borohydride with another reducing agent, lithium borohydride. OH 1. NaBHa, EtOH 2. H3O OCH3 IOCH OH OCH3 OH
Question 3 1 points What would be the main product of the lithium aluminum hydride reduction of this compound? 1) LIATH 2) H30* HO
Give a balanced equation for the reaction that includes both the oxidizing agent (benzil) and reducing agent (NaBH4). In other words I do not want to see 4 R2C=O. Give a brief definition/explanation of reduction in terms of gain/loss of hydrogens, oxygen, and electrons. Sodium borohydride can be used in ethanol solutions to rapidly reduce aldehydes and ketones at room temperature. Even though lithium aluminum hydride (LiAlH4) is much more reactive than sodium borohydride (NaBH4) it can’t be used to reduce aldehydes...
