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 substrater 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...

We performed a synthesis of methyl diantilis lab. The first step
involved a Sodium Borohydride Reduction of
3-Ethoxy-4-hydroxybenzaldehyde (Ethylvanillin) shown below.
The next step of the experiment involved Etherification of
3-ethoxy-4-hydroxylbenzyl Alcohol using one of four alcohols
(methanol, ethanol, 1-propanol, or 2-propanol). The alcohol I used
was methanol. The reaction is predicted below.
Below is the NMR sample for my product with the integration and
ppm for each peak displayed.
Based on this information, answer the following questions.

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...
