In a sodium borohydride reduction of Benzil to get isomers of hydrobenzoin, what is the limiting reagent?I'm trying to find the theoretical yield of the product when sodium borohydride and ethanol are added to benzyl to get hydrobenzoin, but I'm not entirely sure when I am to used 500 mg of benzyl and 100 mg of sodium borohydride and 5 mL of ethanol. Could you help me figure out what it would be?
