What are the products formed when an aldehyde (R CHO ) is reacted with Tollen's reagent?

Options

  1. AAg , H ₂ O , R CH ₂ OH , NH ₃
  2. BAg , H ₂ O , R COO ⁻, H ₂
  3. CAg , H ₂ O , RCOO^ - , NH _ 3
  4. DAg ₂, H ₂ O , RCOO ⁻, NH ₃

Correct answer

C. Ag , H ₂ O , RCOO^ - , NH _ 3

Step-by-step solution

When an aldehyde (R- CHO ) reacts with Tollen's reagent, the following reaction takes place : aligned & R- CHO + (Tollen's reagent) 2 [ Ag ( NH ₃ )₂ ]⁺ +3 OH ⁻ & R COO ⁻+2 Ag +4 NH ₃+2 H ₂ O aligned Thus, the products formed are, Ag , H ₂ O , R COO ⁻ and NH ₃ and option (c) is the correct answer.
