Ammoniacal $AgNO_3$

Vedclass · Answer

(C) Propene and propyne can be distinguished by using the Ammoniacal silver nitrate test. Propyne $(CH_3-C \equiv CH)$ contains a terminal acidic hydrogen atom. Due to the $sp$ hybridization of the terminal carbon,the hydrogen is acidic and reacts with Ammoniacal $AgNO_3$ (Tollens' reagent) to form a white precipitate of silver propynide $(CH_3-C \equiv CAg)$. Propene $(CH_3-CH=CH_2)$ does not contain an acidic hydrogen and therefore does not react with Ammoniacal $AgNO_3$ to form a precipitate.
