Does acetylene react with Fehling's solution ?

Text Solution

Verified by Experts

No, because Fehling's solution contains `Cu^(2+)` ions which do not react with acetylene. Acetylene reacts with only `Cu^+` ions. That is why it gives red ppt. of copper acetylide with ammoniacal CuCl solution and not with Fehling's solution.
