Vedclass · Answer

(D) Propene and propyne can be distinguished by using the Ammoniacal silver nitrate test (Tollens' reagent).Propyne $(CH_3-C \equiv CH)$ contains a terminal acidic hydrogen atom.This acidic hydrogen reacts with Ammoniacal silver nitrate ($AgNO_3$ in $NH_4OH$) to form a white precipitate of silver propynide $(CH_3-C \equiv C-Ag)$.Propene $(CH_3-CH=CH_2)$ does not contain an acidic hydrogen and therefore does not react with Ammoniacal silver nitrate to form a precipitate.

Which of the following reagents is used to distinguish propene and propyne?
