Which is the product obtained, when Br2 water reacts with glucose?
पर्याय
1,6-dlbromo glucose
Saccharic acid
Gluconic acid
Bromohexane
MCQ
उत्तर
Gluconic acid
Explanation:
When Br2 water interacts with glucose, gluconic acid is formed.
\[\begin{array}{cc}
\ce{CHO}\phantom{.............}\ce{COOH}\phantom{..}\\
|\phantom{..................}|\phantom{.......}\\
\ce{(CHOH)4 ->[Br2 water][oxidation] (CHOH)4}\\
|\phantom{..................}|\phantom{.......}\\
\phantom{....}\ce{\underset{\text{D-glucose}}{CH2OH}}\phantom{.........}\ce{\underset{\text{Gluconic acid}}{CH2OH}}
\end{array}\]
Glucose is oxidised to a six-carbon carboxylic acid when it reacts with Br2 water. This suggests that the current carbonyl group is an aldehydic group.
