C₂H₄ and CH₄ will come out of the tube unaffected.
Explanation:
- The ammoniacal cuprous chloride is a reagent used for Glaser coupling.
- It reacts with the terminal alkynes and the acetylene to form dienes.
- The alkynes react with the reagent because of the presence of acidic hydrogen.
- The alkanes and alkenes cannot react because of the absence of acidic hydrogen.
- So, the methane and the methene cannot react with the reagent.
- So they will come out of the reagent unaffected.
