Question:
The reagent which distinguishes formic acid and acetic acid is
The reagent which distinguishes formic acid and acetic acid is
Show Hint
Formic acid behaves like aldehyde → shows reducing nature.
Updated On: Apr 16, 2026
- 2,4-dinitrophenyl hydrazine
- HgCl$_2$
- C$_2$H$_5$ONa
- Hg$_2$Cl$_2$
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Formic acid shows reducing property while acetic acid does not.
Step 1: Reaction with HgCl$_2$.
Formic acid reduces HgCl$_2$.
Step 2: Acetic acid.
Acetic acid does not show this behaviour.
Step 3: Conclusion.
HgCl$_2$ distinguishes the two.
