Vedclass · Answer

(C) Ammoniacal cuprous chloride (Tollens' reagent for alkynes) reacts with terminal alkynes to form a red precipitate of copper acetylide.$2NH_4OH + Cu_2Cl_2 	o 2CuOH + 2NH_4Cl$$CuOH + 2NH_4OH 	o [Cu(NH_3)_2]OH + 2H_2O$$HC \equiv CH + 2[Cu(NH_3)_2]OH 	o CuC \equiv CCu + 4NH_3 + 2H_2O$Since $C_2H_2$ (acetylene) is a terminal alkyne,it forms the copper derivative (copper acetylide).

When treated with ammoniacal cuprous chloride,which one among the following forms a copper derivative?
