D-Allose and D-glucose are stereoisomers. In the open chain form, hexose sugars have four chiral centres. Glucose and allose differ in the stereochemistry only at carbon three and are hence called C3 epimers. Concept introduction: When D-glucose is treated with nitric acid, oxidation of D-glucose takes place. The aldehyde and alcohol group of glucose are oxidized to carboxylic acids forming D-glucaric acid and similarly Allose oxidised to D-Allose acid on treatment with dilute nitric acid.

Question

Curved arrows are used to illustrate the flow of electrons. Using the provided starting and product structures, draw the curved electrons-pushing arrows for the following reaction or mechanistic step(s).

Answer 1

Question

Definition Definition Class of organic compounds that contain a carboxyl group ( - COOH ) and has a general formula R - COOH or R - CO 2 H , where R refers to the alkyl, alkenyl, aryl, or other groups. They can undergo different chemical reactions, such as acid-base reactions, esterification, and oxidation. These are essential components of living organisms, playing important roles in metabolic processes, signaling, and as pharmaceuticals.
