The D-aldopentose which on oxidation produces optically active aldaric acid and that undergoes Wohl Degradation to yield D-aldotetrose which on oxidation produces optically active aldaric acid is to be predicted. Concept introduction: Carbohydrates containing aldehydes are known as aldoses. Wohl Degradation is a method of shortening the aldose by one carbon atom by cleavage of C1 − C2 bond.

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.

For each reaction below, decide if the first stable organic product that forms in solution will create a new CC bond, and check the appropriate box. Next, for each reaction to which you answered "Yes" to in the table, draw this product in the drawing area below. Note for advanced students: for this problem, don't worry if you think this product will continue to react under the current conditions - just focus on the first stable product you expect to form in solution. ?
