Question

Which reagent converts sugar to osazone?
​

Answer 1

Explanation:

during anaerobic respiration or in Absence of o2

Answer 2

Final answer: Phenylhydrazine

Given that: We are given Osazone.

To find: We have to find reagent that converts sugar to Osazone.

Explanation:

• Osazones are the organic chemical compound coming under the class of carbohydrate derivatives.
• Osazones are formed by when reducing sugars are reacted with excess amount of phenylhydrazine at boiling temperatures.
• The formation of Osazones containing pair of hydrazone functionalities, which involves both oxidation and condensation reactions.
• Only reducing sugars are participate in this reaction because the reaction requires a free carbonyl group. Non reducing sugars such as sucrose does not form an Osazone.
• This Osazone formation test is used to identify monosaccharides. Osazones are highly coloured crystalline compounds. So we can readily distinguishes the Osazones compounds.

• Osazone formed from maltose is Maltosazone which is petal-shaped crystals.

• Osazone formed from lactose is Lactosazone which is powder puff-shaped crystals.

• Osazone formed from galactose is Galactosazone which is rhombic-plate shaped crystals.

• Osazone formed from glucose, fructose or mannose is Glucosazone which is broomstick or needle-shaped crystals.
