A) Cu
B) \[C{{u}_{2}}O\]
C) \[CuO\]
D) \[C{{u}_{3}}O\]
Correct Answer: B
Solution :
\[C{{H}_{3}}CHO+2CuO\to C{{H}_{3}}COOH+C{{u}_{2}}O\downarrow \] Hence in the reaction, precipitate of copper oxide\[(C{{u}_{2}}O)\]is formed. Fehling solution is an alkaline solution of cupric ion complexed with sodium potassium tartrate. Hence, the correct option is (b).You need to login to perform this action.
