Vedclass · Answer

(B) The reaction of ethyne $(HC \equiv CH)$ with ammoniacal silver nitrate $(AgNO_3 + NH_4OH)$ is a characteristic test for terminal alkynes.Terminal alkynes have acidic hydrogen atoms.These hydrogen atoms are replaced by silver ions to form silver acetylide $(Ag_2C_2)$,which appears as a white precipitate.The balanced chemical equation is:$HC \equiv CH + 2AgNO_3 + 2NH_4OH \rightarrow AgC \equiv CAg + 2NH_4NO_3 + 2H_2O$Thus,'$X$' is $Ag_2C_2$.

In the reaction $HC \equiv CH + 2AgNO_3 \xrightarrow{NH_4OH} X + 2NH_4NO_3 + 2H_2O$,'$X$' is:
