When ethyne is treated with ammonical Cu2Cl2 solution, then ppt of dicopper acetylide are formed. The colour of ppt is?
Correct answer: B. Reddish brown
- A. White
- B. Reddish brown
- C. Yellow
- D. Violet
Explanation
When ethyne reacts with ammonical Cu2Cl2 solution, dicopper acetylide is formed, which appears reddish brown in color. The reaction results in the formation of this specific compound, leading to the characteristic color change. The other options (white, yellow, and violet) do not accurately represent the color of dicopper acetylide in this chemical reaction.
