Hydrazine reduce Fehling's solution to form: (a). Cu(OH) (b) Cu_2O (c). CuO (d). Cu+O_2

(A) : Acetaldehyde reduces Fehling's solution but benzaldehyde dose not. (R) : Acetaldehyde is a stronger reducing agent then benzaldehyde .

Fehling’s solution –B is-

Fructose reduces Fehling's solution due to the presence of :

Assertion : Glucose reacts with phenyl hydrazine and Fehling's solution but not with NaHSO_(3) . Reason : NaHSO_(3) cannot break the ring structure.
