Vedclass · Answer

(D) Tollen's reagent is an ammoniacal silver nitrate solution,$[Ag(NH_3)_2]^+OH^-$.It acts as a mild oxidizing agent.Aldehydes are oxidized to corresponding carboxylate ions by Tollen's reagent,while the silver ions are reduced to metallic silver,which deposits on the inner walls of the test tube as a '$Silver mirror$'.Since $Glucose$ gives a positive '$Silver mirror$' test,it confirms the presence of an aldehyde group in its open-chain structure.

$Glucose + \text{Tollen's reagent} \to \text{Silver mirror}$ shows:
