Q. Among the given compounds, one which can be distinguished by $A g N O_{3}$ is

ethane

ethylene

acetylene

diethyl ether

Only acetylene reacts with $A g N O_{3}$ and gives white precipitate of silver acetylide among the given compounds.
$C H \equiv C H A g N O_{3} + N H_{4} O H white ppt C A g \equiv C A g$
Thus, it is distinguished by $A g N O_{3} .$
