Vedclass · Answer

(A) Acetylene $(HC \equiv CH)$ reacts with ammoniacal silver nitrate $(AgNO_{3} + NH_{4}OH)$ to form a white precipitate of silver acetylide $(AgC \equiv CAg)$.The chemical reaction is:$HC \equiv CH + 2AgNO_{3} + 2NH_{4}OH \rightarrow AgC \equiv CAg + 2NH_{4}NO_{3} + 2H_{2}O$This reaction is specific to terminal alkynes,which have acidic hydrogen atoms,and results in the formation of a white precipitate of silver acetylide.

Acetylene reacts with ammoniacal $AgNO_{3}$ to form:
