Question

Write the product when $D$-glucose reacts with conc. $HN{O}_3$.

Answer 1

Hint: Oxidation is defined as the lack of electrons through a response with the aid of a molecule, atom or ion. Oxidation takes place when the oxidation kingdom of a molecule, atom or ion is hastened. The opposite procedure is referred to as reduction, which happens when there is a gain of electrons or the oxidation state of an atom, molecule, or ion decreases.

Complete step by step solution:
When $D$-glucose reacts with conc. $HN{O}_3$ , saccharin acid is obtained which is also known as Glucaric acid. In this reaction, Aldehydic group and primary alcoholic group of glucose are oxidized to carboxylic group as shown below:

Additional information:
Carboxylic acid, which is a class of organic compounds in which a carbon atom is attached to an oxygen atom by a double bond and to a hydroxyl group by a single bond. A fourth bond links the carbon atom to a hydrogen atom or to some other univalent combining group. The carboxyl group is named as this because of the presence of carbonyl group and hydroxyl group.
Carboxylic acids arise largely in nature. The fatty acids are additives of glycerides, which in casual are additives of fat. Hydroxyl acids, along with lactic acid (present in bitter-milk merchandise) and citric acid (present in citrus end result), and many keto acids are important metabolic products that exist in maximum dwelling cells. Proteins are made from amino acids, which moreover include carboxyl groups.

Note:
Compounds in which the hydroxyl of the carboxyl group is changed via positive different organizations are called as carboxylic acid derivatives and the maximum essential of those are acyl halides, acid anhydrides, esters, and amides.
