Question

Red precipitate is formed when acetylene passes through ammonical cuprous chloride solutions is:

• A. $C_2{H}_2$
• B. $C_2{H}_6$
• C. $C_2{H}_4$
• D. $C{H}_4$

Answer 1

The correct option is A $C_2{H}_2$

Acetylides of heavy metals are easily formed by reaction of acetylene with the metal ions. Reaction of acetylene with ammonical cuprous chloride solution gives copper acetylide of red precipitate and it is very dangerous explosive.
