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...

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...
