For the reduction of benzophenone to benzohydrol by NaBH4
1) Draw the reaction, showing the reactants and products. • What apparatus and conditions (solvent, temp., reaction time, etc) will be used for the reaction? (we are using ethanol and Buchner funnel filtration)
• How will the benzhydrol product be isolated from the reaction mixture and how will it then be further purified?
How will the product be characterized?
• Identify which is the reducing agent and which is the oxidizing agent in the reaction of benzophenone with sodium borohydride and explain your reasoning, ie. show the changes in oxidation states (best to give a drawing as per the introduction)?
• give the mechanism of the reaction, indicate what bonds are broken/formed and draw arrows to show what happens to the electrons as bonds break and form.

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...
