Question

By which of the following reagents, both the aldehyde and the primary alcoholic group of glucose are oxidized? (A) Tollen's reagent (B)  Br2+H2O  (C)  HNO3  (D) All of these

Tardigrade Admin · Accepted Answer

Tollen's reagent and bromine water both are mild oxidising agent, thus oxidise only aldehyde group. HNO3, being strong oxidizing agent, oxidises both the aldehyde as well as the primary alcoholic group and gives glucaric acid.

Q. By which of the following reagents, both the aldehyde and the primary alcoholic group of glucose are oxidized?

Tollen's reagent

$B r_{2} + H_{2} O$

$H N O_{3}$

All of these

Tollen's reagent and bromine water both are mild oxidising agent, thus oxidise only aldehyde group. $H N O_{3},$ being strong oxidizing agent, oxidises both the aldehyde as well as the primary alcoholic group and gives glucaric acid.
