Ammoniacal $AgNO_3$

Vedclass · Answer

(C) $CH_3CH=CHCHO$ is an $\alpha,\beta$-unsaturated aldehyde. Ammoniacal $AgNO_3$ (Tollens' reagent) is a mild oxidizing agent that selectively oxidizes the aldehyde group to a carboxylic acid group without affecting the carbon-carbon double bond. The reaction is: $CH_3CH=CHCHO + 2[Ag(NH_3)_2]^+ + 3OH^- 	o CH_3CH=CHCOO^- + 2Ag + 4NH_3 + 2H_2O$. Alkaline $KMnO_4$ is a strong oxidizing agent and would likely cleave the double bond. Selenium dioxide is typically used for allylic oxidation. Therefore,the correct reagent for this specific transformation is Ammoniacal $AgNO_3$.
