What is the action of the following reagents on glucose? (a) bromine water(b) dilute HNO_(3) hydroxyl amine

Answer»

Solution :(a) Bromine water : When glucose reacts with bromine water, GLUCONIC acid is formed.
`underset("Glucose")(CH_(2)OH) (CHOH)_(4) CHO + [O] overset(Br_(2)//H_(2)O)(to) underset("Gluconic acid")(CH_(2)OH (CHOH)_(4)) COOH`
(b) Dilute `HNO_(3)` : When D-Glucose is treated with nitric acid, oxidation of D-Glucose TAKES place. The aldehyde and alcohol group of glucose are ozidized to carboxylic acids forming D-Glucaric acid.

(C ) Hydroxylamine : D (+) glucose reacts with hydroxyl AMINE and yield an oxime. The structure of the oxime would be:
