Briefly define oxidation and reduction. Can an oxidation occur without a simultaneous reduction? Why or why not?
Homework Answers
Oxidation is the loss of electrons by an element and reduction is a gain of electrons. Oxidation cannot occur without a simultaneous reduction because free electrons are unstable. When the oxidised substance loses electrons, these electrons have to be accepted by another substance and cannot be free.

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...
