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