the experiment is the reduction of 2-methylcyclohexanon with sodium borohydride. the HNMR is for the product of the reaction. what is the product and the integration 3.07 3.66 93.27 3.07 3.66 93.27
From experiment reduction of camphor 2. The major products from the sodium borohydride reduction can be predicted by the effect called 'steric approach control'. However, the major product from the reduction of 4-t-butylcyclohexane is not determined by this factor. Explain.
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...
