What is Tollen's reagent? Write the chemical equation of the reaction of aldehyde with Tollen's reagent.
What is Tollen's reagent? Write the chemical equation of the reaction of aldehyde with Tollen's reagent.
Show Hint
Tollen's test is used to distinguish aldehydes from ketones as only aldehydes undergo oxidation.
Solution and Explanation
Step 1: Definition:
Tollen's reagent is an ammoniacal silver nitrate solution that oxidizes aldehydes to carboxylates, forming a silver mirror.
Step 2: Reaction: \[ R-CHO + 2[Ag(NH_3)_2]^+ + 3OH^- \rightarrow R-COO^- + 2Ag + 4NH_3 + H_2O \]
