Chemistry - Biomolecules Question with Solution | TestHub

Here only$\left(\mathrm{B}\right)$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 and oxidation of glucose with$\mathrm{H}\mathrm{N}{\mathrm{O}}_3$gives Saccharic acid.
