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 \[\text{CC}{{\text{l}}_{\text{4}}}\]
Correct Answer: C
Solution :
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\[\text{AgN}{{\text{O}}_{\text{3}}}.\]
