18 Question (1 point) Draw the product that results from the following reaction. NaBH4 ethanol C)
The reduction of ethyl acetoacetate with sodium borohydride is show below. Explain why the product of the reaction does not have two alcohol functional groups. QH NaBH4 ethanol, 0°C
Sodium Borohydride Reduction of Benzoin Pre-Lab Worksheet (1) Why is it important to use 100% ethanol for this reaction? 5, ethanol (absolute ethanol) rather than 95% of benzoin? ow would you expect the IR spectrum of the reduced product to differ from that 7. (2) How would you expect the 1H rom that of benzNMR spectrum of the reduced product to differ 8. (2) How many peaks do you expect in the 13C NMR spectrum of the product? Suppose you...

EXPERIMENT 11 THE MICROSCALE REDUCTION OF BENZIL WITH SODIUM BOROHYDRIDE INTRODUCTION Oxidation-reduction (redox) reactions occur in concert. One substance undergoes oxidation by donating electrons to another substance that is then reduced. In organic chemistry certain rules are followed in determining whether a particular substrate is being oxidized or reduced. Oxidation: The loss of hydrogen and/or gain of oxygen by a substrate Reduction: The gain of hydrogen and/or loss of oxygen by a substrate When an organic substrate is reduced, the...
hi, please help me with number 7. thank you EXPERIMENT SEVEN SODIUM BOROHYDRIDE REDUCTION OF ACETOPHENONE HOCH, DISCUSSION The reduction of an aldehyde or ketone with sodium borohydride is straight forward and usually affords a high yield of the alcohol. The usual procedure (and the one employed in this experiment) involves dissolving the borohydride in 95% ethanol and adding the carbonyl compound to this solution. To ensure complete reaction, an excess of sodium borohydride is used. The reaction between sodium...
