Question:
Which of the following reagents will oxidise glucose to gluconic acid?
Br$_2$/H$_2$O
HNO$_3$
[Ag(NH$_3$)$_2$]^+ / OH$^-$
Which of the following reagents will oxidise glucose to gluconic acid?
Br$_2$/H$_2$O
HNO$_3$
[Ag(NH$_3$)$_2$]^+ / OH$^-$
Br$_2$/H$_2$O
HNO$_3$
[Ag(NH$_3$)$_2$]^+ / OH$^-$
Show Hint
Gluconic acid formation requires mild oxidation of the aldehyde group only, not the entire molecule.

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
\begin{itemize}
\item \(Br$_2$/H$_2$O\) and Tollen's reagent \([Ag(NH$_3$)$_2$]^+\) oxidize the aldehyde group of glucose to gluconic acid.
\item HNO$_3$ is a strong oxidizing agent; it oxidizes both -CHO and -CH$_2$OH to dicarboxylic acids, not just gluconic acid.
\end{itemize}

Top Questions on Biomolecules
- Ribose and 2-deoxyribose have an important role in biology. Among the most important derivatives are those with phosphate groups attached at the 5 position. Mono-, di- and tri-phosphate forms are important, as well as 3-5 cyclic monophosphates. Purines and pyrimidines form an important class of compounds with ribose and deoxyribose. When these purine and pyrimidine derivatives are coupled to a ribose sugar, they are called nucleosides.
