Question

D(+)-glucose reacts with hydroxyl amine and yields oxime. What would be the structure of the oxime?

Answer 1

Hint: The molecular formula of hydroxyl amine is\[N{{H}_{2}}OH\]. Generally hydroxyl amine reacts with carbonyl carbon and forms respective oxime as a product. Glucose also reacts with hydroxyl amine due to the presence of the aldehyde functional group in D(+)-glucose.

Complete step by step answer:
-The structure of D(+)-glucose is as follows.

-The D(+)-glucose contains aldehyde groups in its structure.
-Then the aldehyde reacts with hydroxylamine and forms aldoxime structure.
-The chemical reaction of D(+)-glucose with hydroxylamine is as follows.

-The structure of the glucoxime is as follows.

Additional information:
-Almost maximum oximes are solids in nature and it is useful to find the presence of aldehyde or ketone functional groups in the given compound.
-Oximes are colorless crystals and less soluble in water.
-Oxime derivatives are used as medicines for nerve agents (A nerve agent deactivates acetylcholinesterase by phosphorylation reaction).
-Oximes are the chemical derivatives and belong to the category of imines.
-Dimethylglyoxime is a famous oxime used in the analysis of nickel.
-Occasionally oximes involves in multistep chemical synthesis to guard carbonyl compound
-Oximes exhibit both acidic (Weak acid) and base properties and are toxic in nature.
-Oximes are going to decompose while heating and create massive explosions.

Note: In Japan, perillaldehyde (an oxime) is used as an artificial sweetener. Methyl ethyl ketoxime is used in oil paints and as a preservative for avoiding the skin from chemicals. Acetone oxime is used to reduce the corrosion which reduces the toxicity.
