Question

Propyne and propene can be distinguished by

• A. $ \text{dil}\text{.}\,\text{KMn}{{\text{O}}_{4}} $
• B. $ \text{conc}\text{.}\,{{\text{H}}_{\text{2}}}\text{S}{{\text{O}}_{\text{4}}} $
• C. $ \text{AgN}{{\text{O}}_{\text{3}}} $ in ammonia
• D. $ \text{B}{{\text{r}}_{\text{2}}} $ in $ \text{CC}{{\text{l}}_{\text{4}}} $

Answer 1

Answer: (C)

Propyne and propene can be distinguished by $ \text{AgN}{{\text{O}}_{\text{3}}} $ in ammonia. Propyne gives a white precipitate with ammoniacal silver nitrate while propene has no effect on ammoniacal $ \text{AgN}{{\text{O}}_{\text{3}}}. $
