Which of the following statements is incorrect regarding the reaction? aligned & CH ₃ CHO + [ Ag ( NH ₃ )₂ ]^ + OH & CH ₃ COO ⁻+ Ag & aligned
Options
- AThe equivalent weight of CH ₃ CHO is 22
- BThree moles of OH ⁻ are required in the above reaction
- CCH ₃ CHO is an oxidising agent
- DReduction of [ Ag ( NH ₃ )₂ ]^ occurs
Correct answer
C. CH ₃ CHO is an oxidising agent
Step-by-step solution
Oxidation: CH ₃ CHO +3 OH ⁻ CH ₃ COO ⁻+2 e ⁻+2 H ₂ O ...(i) Reduction: [ Ag ( NH ₃ )₂ ]⁺+ e ^ Ag +2 NH ₃ 2 ...(ii) aligned & CH ₃ CHO + [ Ag ( NH ₃ )₂ ]^ +3 OH & CH ₃ COO ⁻+2 H ₂ O +2 Ag +4 NH ₃ & aligned Molecular mass of CH ₃ CHO =44 Equivalent weight = M W n -factor = 44 2 =22 Therefore, acetaldehyde is not an oxidising agent.
