A) Cu
B) CuO
C) \[C{{u}_{2}}O\]
D) \[Cu{{(OH)}_{2}}\]
Correct Answer: C
Solution :
Acetaldehyde reacts with Fehling solution to give red ppt. of cupric oxide. \[C{{H}_{3}}CHO+\underbrace{2C{{u}^{2+}}+5O{{H}^{-}}}_{Fehling\text{ }solution}\xrightarrow{{}}\] \[C{{H}_{3}}\underset{red\text{ }ppt.}{\mathop{CO{{O}^{-}}+C{{u}_{2}}O+3{{H}_{2}}O}}\,\]You need to login to perform this action.
