A) \[CuO\]
B) \[C{{u}_{2}}O+CuO\]
C) \[Cu\]
D) \[C{{u}_{2}}O\]
Correct Answer: D
Solution :
\[\underset{Ethanol}{\mathop{C{{H}_{3}}CHO}}\,+\underset{\begin{smallmatrix} Fehlings \\ solution \end{smallmatrix}}{\mathop{2C{{u}^{2+}}}}\,+5O{{H}^{-}}\xrightarrow{{}}\] \[C{{H}_{3}}CO{{O}^{-}}+3{{H}_{2}}O+\underset{\begin{smallmatrix} Cupprous\,oxide \\ (\operatorname{Red}\,ppt) \end{smallmatrix}}{\mathop{C{{u}_{2}}O}}\,\]
