In the synthesis of benzil Quinoxaline, I produced 0.38 g, when the reagents were Benzil (0.20 g) and 1,2 phenylendiamine (o.10 g) this is obviuosly impossible due to limiting reagents, but is there any explanation as to why this happened?

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...
