    Among the given compounds, one which can be distinguished by \[\text{AgN}{{\text{O}}_{\text{3}}}\]is

    A)  ethane                               

    B)  ethylene

    C)  acetylene          

    D)  diethyl ether

    Correct Answer: C

    Solution :

                     Only acetylene reacts with \[AgN{{O}_{3}}\]and gives white precipitate of silver acetylide among the given compounds. \[CH\equiv CH\xrightarrow[+N{{H}_{4}}OH]{AgN{{O}_{3}}}\underset{white\,ppt}{\mathop{CAg\equiv CAg}}\,\] Thus, it is distinguished by \[AgN{{O}_{3}}.\]
