One molecule of NaBH4 can in theory reduce four ketone functional groups. If you had 25 mg of NaBH4, how many many mg of benzil could be fully reduced?
How many stereo centers are in the following molecule (can you explain why) ОН
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...
Write two balanced equations: (step 1) reaction of benzil with NaBH4 to form a “dialkoxide” and (step 2) reaction of the formed “dialkoxide” with water to produce hydrobenzoin. NaBH4 is the source of four equivalents of the hydride ion, H-
During EMP glycolysis, 1 molecule of glucose is broken down into two molecules of pyruvate and 2 molecules of NADH are produced. During fermentation, 1 molecule of pyruvate is reduced. During this process, one molecule of NADH is oxidized. If 34 molecules of glucose are broken down during glycolysis, and all the resultant molecules of pyruvate are reduced by fermentation, how many molecules of NADH will remain?
Why are there two ATP molecules formed for one molecule of glucose?
