The D-aldohexoses that yield the products formed by the given conditions are to be determined. Concept introduction: Reduction of monosaccharides with sodium borohydride reduces the aldehyde group to primary alcohol. Oxidation of monosaccharides with bromine oxidizes the aldehyde group to carboxylic acid . Oxidation of monosaccharides with nitric acid oxidizes the aldehyde group as well as the terminal -CH 2 OH to carboxylic acid groups. Carbohydrates undergo enolization in the open-chain form. The aldehyde oxygen is protonated by the hydrogen from C2, converting it to hydroxyl group and forming a double bond between C1 and C2. Carbohydrates that differ in configuration only at C2 give the same enediol. A molecule with more than one chirality center can be optically inactive if it has a plane of symmetry of a center of symmetry.

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.
