Question
With ammoncal cuprous chloride solution, a reddish precipitate is obtained on treatingwith:
Options
A.CH4
B.C2H4
C.C2H2
D.C2H6
Solution
Acetylene forms brown copper acetylene with ammonical cuprous chloride solution
Cu2Cl2 + C2H2 → Cu2C2 + 2HCl
2HCl + 2NH4OH → 2NH4Cl + 2H2O
Cu2Cl2 + C2H2 → Cu2C2 + 2HCl
2HCl + 2NH4OH → 2NH4Cl + 2H2O
