Write the reaction involved when D-glucose is treated with the following reagent:
Br2 water
What happens when D-glucose is treated with the following reagent?
Bromine water
उत्तर
When glucose is heated with bromine water, it is oxidised to gluconic acid, a six-carbon carboxylic acid.
\[\begin{array}{cc}
\phantom{........}\ce{CHO}\phantom{.............}\ce{COOH}\phantom{..}\\
\phantom{.}|\phantom{..................}|\\
\phantom{.......}\ce{(CHOH)4->[Br2 water](CHOH)4}\\
\phantom{.}|\phantom{..................}|\\
\phantom{.............}\ce{\underset{\text{D-glucose}}{CH2OH}}\phantom{........}\ce{\underset{\text{D-gluconic acid}}{CH2OH}}\phantom{.}
\end{array}\]
