Question

Propene and propyne can be distinguished by

• A. $B{r}_2/CC{l}_4$
• B. $Baye{r}^{\prime }sReagent$
• C. $AgN{O}_3+N{H}_{4}OH$
• D. $O_3$

Answer 1

The correct option is C $AgN{O}_3+N{H}_{4}OH$

correct answer is option (c).

Propyne is terminal alkyne so it gives white precipitate with ammonical silver nitrate solution but alkene does not.Thus propene and propyne can be distinguished by ammonical silver nitrate solution.
