Question

Acetylene reacts with ammonia acid copper chloride to give a precipitate of

Answer 1

Acetylene(Ethyne) reacts with ammoniacal cuprous chloride solution to form a red precipitate of Copper Acetylide

C2H2 + 2(CuCl) + 2(NH4OH) = C2Cu2 + 2(NH4Cl) + 2(H20)

Hope it helps :)

Answer 2

Acetylene reacts with ammonia acid copper chloride to give a precipitate of Copper Acetylide.

Explanation:

• Acetylene or Ethyne reacts with ammonical cuprous chloride solution to form a red precipitate of Copper Acetylide
• $C_{2}H_{2} + 2(CuCl) + 2 NH_{4}OH ------ C_{2}Cu_{2} + 2 NH_{4} Cl + 2H_{2}O$
• When ammoniacal cuprous chloride reacts with acetylene it gives But -1,3-yne.

• Acetylene is passed through an ammonical solution of cuprous chloride at room temperature, which gives red precipitates of copper acetylides.

• It is an explosive when dry formed
