A) \[C{{u}_{2}}O\]
B) \[Cu\]
C) \[CuO\]
D) \[CuS{{O}_{4}}\]
Correct Answer: A
Solution :
When acetaldehyde is heated with Fehling solution, a red precipitate of \[C{{u}_{2}}O\] is obtained. \[C{{H}_{3}}CHO+2Cu{{(OH)}_{2}}+NaOH\xrightarrow{{}}\] \[C{{H}_{3}}COONa+\underset{red}{\mathop{C{{u}_{2}}O}}\,\downarrow +3{{H}_{2}}O\]You need to login to perform this action.
