    When ethanol is treated with Fehling's solution, it gives a precipitate of

    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).
