उत्तर

Glucose gets oxidised to a six carbon monocarboxylic acid called gluconic acid on reaction with bromine water which is a mild oxidizing agent.

\phantom{}|\phantom{.......................}|\phantom{......}\\
\phantom{}\ce{(CHOH)4 + [O] ->[Br2 water]\phantom{}(CHOH)4}\phantom{}\\
\phantom{}|\phantom{.......................}|\phantom{......}\\
\phantom{..}\ce{\underset{\text{Glucose}}{CH2OH} \phantom{...............}\underset{\text{Gluconic acid}}{CH2OH}}\phantom{}
