A) \[K[Cu{{(CN)}_{6}}]\]
B) \[CuCN\]
C) \[CuC{{N}_{2}}\]
D) \[{{K}_{3}}[Cu{{(CN)}_{4}}]\]
Correct Answer: D
Solution :
\[2CuS{{O}_{4}}+10KCN\to \underset{\text{Potassium}\,\text{cuprocyanide}}{\mathop{2{{K}_{3}}[Cu{{(CN)}_{4}}]}}\,+2{{K}_{2}}S{{O}_{4}}\] Hence, the correct option is [d].You need to login to perform this action.
