Vedclass · Answer

(C) Acetylene $(CH \equiv CH)$ reacts with ammoniacal cuprous chloride to form a red precipitate of copper acetylide $(Cu-C \equiv C-Cu)$.$CH \equiv CH + 2[Cu(NH_3)_2]OH 	o Cu-C \equiv C-Cu + 4NH_3 + 2H_2O$Methane $(CH_4)$ and ethylene $(C_2H_4)$ do not possess acidic hydrogen atoms and therefore do not react with ammoniacal cuprous chloride.$CH_4 + 	ext{Ammoniacal } Cu_2Cl_2 	o 	ext{No reaction}$$C_2H_4 + 	ext{Ammoniacal } Cu_2Cl_2 	o 	ext{No reaction}$Thus,the gases that pass through the bottle without reacting are methane and ethylene.

$A$ mixture of methane,ethylene,and acetylene gases is passed through a Wolf's bottle containing ammoniacal cuprous chloride. The gas coming out is
