A) White precipitate with \[AgN{{O}_{3}}\] and red precipitate with \[C{{u}_{2}}C{{l}_{2}}\]
B) White precipitate with \[C{{u}_{2}}C{{l}_{2}}\] and red precipitate with \[AgN{{O}_{3}}\]
C) White precipitate with both the reagents
D) Red precipitate with both the reagents
Correct Answer: A
Solution :
\[C{{H}_{3}}\equiv \,\,\,CH\,\,\,+\underset{\text{(Ammonical)}}{\mathop{AgN{{O}_{3}}}}\,\to \underset{\text{White ppt}\text{.}}{\mathop{Ag-C\equiv C-Ag}}\,\] \[C{{H}_{3}}\equiv CH\,\,\,+\underset{\text{(Ammonical)}}{\mathop{CuC{{l}_{2}}}}\,\to \underset{\text{Red ppt}\text{.}}{\mathop{Cu-C\equiv C-Cu}}\,\]
