4) In organic chemistry, oxidation refers to the addition of oxygen or removal of hydrogen. While reduction refers to addtition of hydrogen or removal of oxygen.
We take example of ethanal to show both oxidation and reduction.
ethanal undergoes reduction in presence of LiAlH4 to give ethanol.
ethanal undergoes oxidation in presence of K₂Cr₂O₇ to give ethanoic acid

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...
