The distinguishing test for the given compounds is to be determined. Concept Introduction: ▸ The pyranoses are six-membered monosaccharide ring structures. The name signifies heterocycle p y r a n + o s e . ▸ Pyranoses are the hemiacetals having ring structures of the D − (+) − Glucose while glucopyranosides are the carbohydrate acetals called glycosides. ▸ Benedict’s test is a typical chemical method used to oxidize aldoses and ketoses. This particular test can be used as a colorimetric analysis tool and a positive or negative test can help in the distinction of different types of carbohydrates. Tollen’s reagent, which is composed of silver nitrate and ammonia can also selectively oxidize aldehyde and ketone groups present in the carbohydrates. The presence or absence of the oxidized product serves as the basis for the determination of the chemical nature of the compound.

Answer 1

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.

Aldohexoses A and B both undergo Ruff degradation to give aldopentose C. On treatment with warm nitric acid, aldopentose C gives an optically active aldaric acid. B alsoreacts with warm nitric acid to give an optically active aldaric acid, but A reacts to givean optically inactive aldaric acid. Aldopentose C is degraded to aldotetrose D, whichgives optically active tartaric acid when it is treated with nitric acid. Aldotetrose D isdegraded to (+)@glyceraldehyde. Deduce the structures of sugars A, B, C, and D, and useFigure 23-3 to determine the correct names of these sugars.

Identify the hemiacetal function in lactose and show mechanistically how the stereochemistry at that carbon can easily invert, especially in the presence of acids and bases.

An aldose A, is reduced by sodium borohydride to an optically inactive alditol B. The Ruff degredation of A forms C. Oxidation of C by nitric acid generates the optically inactive diacid D. The ruff degreation of C forms D-glyceraldehyde. draw the structures for compounds A through D and discuss a mechanism for the reduction step using sodium borohydride
