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

J & K CETJ & K CET 2009

Solution:

Tollen's reagent and bromine water both are mild oxidising agent, thus oxidise only aldehyde group. $ HNO_3, $ being strong oxidizing agent, oxidises both the aldehyde as well as the primary alcoholic group and gives glucaric acid.
