Ammoniacal cuprous chloride

Vedclass · Answer

(C) Acetylene $(HC \equiv CH)$ is a terminal alkyne with acidic hydrogen atoms.It reacts with ammoniacal cuprous chloride $(Cu_2Cl_2 + NH_4OH)$ to form a red-brown precipitate of copper$(I)$ acetylide $(CuC \equiv CCu)$.Ethylene $(CH_2 = CH_2)$ does not contain acidic hydrogen and does not react with ammoniacal cuprous chloride.Therefore,this reagent is used to distinguish between them.

Which of the following is used to distinguish ethylene and acetylene?
