Q. Which of the following compound cannot reduce Fehling solution?

BHUBHU 2007

Solution:

Aldehyde reacts with Fehling solution to give carboxylic acid and red ppt. of $Cu _{2} O$. But carboxylic acid except formic acid cannot reduce Fehling solution due to the presence of alkyl group in carboxylic acid.
$HCOOH +\underset{\text { Fehling solution }}{2 CuO } \longrightarrow Cu _{2} O + CO _{2}+ H _{2} O$
$CH _{3} COOH +\underset{{\text {Fehling solution }}}{2 CuO} \longrightarrow X$
