Two gas cylinders contain ethylene (ethene) and acetylene respectively. One test which can be used to distinguish between them is by?
- passing each gas through bromine water
- passing each gas through dilute potassium permanganate solution
-
passing each gas through silver nitrate solution
- treating each gas catalytically with excess hydrogen gas
The correct answer is: C
Explanation
Acetylene reacts with ammoniacal AgNO3 solution to form a white precipitate of silver acetylide (AgC-=Cag) but ethylene does not
