Question:
Which of the following reaction does not form benzaldehyde as product?
Which of the following reaction does not form benzaldehyde as product?
Show Hint
Cannizzaro converts aldehydes into alcohol + acid — not aldehyde formation.
Updated On: Apr 14, 2026
- Rosenmund reaction
- Etard reaction
- Gattermann Koch reaction
- Cannizzaro reaction
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
•Rosenmund: acid chloride → aldehyde
•Etard: toluene → benzaldehyde
•Gattermann-Koch: benzene → benzaldehyde
•Cannizzaro: aldehyde → alcohol + acid Cannizzaro reaction does not produce aldehyde, instead: \[ 2 \text{Benzaldehyde} \rightarrow \text{Benzyl alcohol + Benzoic acid} \] \[ \therefore \text{correct answer = Cannizzaro reaction} \]
