In which of the following reagents, cupric citrate complex is formed?
Correct answer: B. Benedict's solution test
- A. Fehling's solution test
- B. Benedict's solution test
- C. Silver mirror test
- D. Sodium nitroprusside test
Explanation
The correct option for the reagent in which the cupric citrate complex is formed is B) Benedict's solution test. Both Fehling's solution and Benedict's solution contain cupric ions complexed with citrate ions, and they are used to test for reducing sugars (particularly aldehydes). The presence of reducing sugars causes the formation of a cupric citrate complex, which is then reduced to cuprous ions, leading to the characteristic color change in the solution.

About Aldehydes and Ketones
Aldehydes and ketones contain the polar carbonyl group, but aldehydes are generally more readily oxidised and more reactive than ketones. Coverage includes preparation by oxidation or reduction routes, nucleophilic addition of reagents such as hydrogen cyanide and bisulfite, and tests that distinguish aldehydes from ketones.
