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...

Fill in the table for me please!!! and what is the
limiting reagent?? thanks!!!
Background Sodium (or potassium) borohydride is a highly selective reagent that reduces aldehydes or ketones to the corresponding alcohels but normally does not reduce nitro, nitrile, olefinic, amide, carboxylic acid, or ester functional groups. The reagent is less reactive (i.e., more selective) than lithium aluminum hydr it may be used in aqueous or alcoholic solutions. Lithium aluminum hydride, on the other hand, reacts violently with such...

Experiment . the reduction of bencil (March 2020) Your name Sodium borohydride is a convert recent for the reduction of dehydes and ketones to 1" and 2 alcohols, respectively. The mechanism of the reaction - (below) is straightforward and is driven by boron's affinity for oxygen. In addition, given borohydride's remarkably low reactivity with OH groups under neutral and especially basic conditions, this reaction can be done in alcohol solvents. This means that (unlike LAH or Grignard reactions) no separate...
