Updated On: Nov 12, 2026
- Etard reaction
- Gattermann-Koch reaction
- Cannizzaro reaction
- Wurtz reaction
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept
Toluene reacts with chromyl chloride \((\text{CrO}_2\text{Cl}_2)\) in \(\text{CS}_2\) to form a chromium complex.
Step 2: Hydrolysis
The complex is hydrolysed to give benzaldehyde.
Step 3: Name
This is the Etard reaction.
Final Answer:
The reaction is the Etard reaction. \[ \boxed{\text{(A) }\text{Etard reaction}} \]
