A) HCOOH
B) \[C{{H}_{3}}COOH\]
C) HCHO
D) \[C{{H}_{3}}CHO\]
Correct Answer: B
Solution :
Aldehyde reacts with Fehling solution to give carboxylic acid and red ppt. of\[C{{u}_{2}}O\]. But carboxylic acid except formic acid cannot reduce Fehling solution due to the presence of alkyi group in carboxylic acid. \[HCOOH+\underset{Fehling\text{ }solution}{\mathop{2CuO}}\,\xrightarrow[{}]{{}}\] \[C{{u}_{2}}O+C{{O}_{2}}+{{H}_{2}}O\] \[C{{H}_{3}}COOH+\underset{Fehling\text{ }solution}{\mathop{2CuO}}\,\xrightarrow[{}]{{}}X\]You need to login to perform this action.
