Question

Which of the following statement is correct?

• A. Gluconic acid is a dicarboxylic acid
• B. Gluconic acid is a partial oxidation product of glucose
• C. Gluconic acid can form cyclic (acetal/hemiacetal) structure
• D. Gluconic acid is obtained by oxidation of glucose with $\text{HN}\text{O}_{3}$

Answer 1

Answer: (B)

Here only $\left(B\right)$ is correct and rest are incorrect. As Gluconic acid is a monocarboxylic acid which is formed by the partial oxidation of glucose.
As Gluconic acid can not form cyclic (acetal/hemiacetal) structure due to absence of aldehyde and ketone.
Oxidation of glucose with $HNO_{3}$ gives Saccharic acid which is dicarboxylic acid. Primary alcohol and aldehyde both get oxidised to carboxylic acid.
