In Etard's reaction, toluene is oxidized to benzaldehyde by
Show Hint
Etard's reaction is a mild oxidation method used to convert toluene to benzaldehyde.
- \( H_2O_2 \)
- \( CrO_2Cl_2 \)
- \( Cl_2 \)
- \( KMnO_4 \)
The Correct Option is B
Solution and Explanation
Step 1: In Etard's reaction, toluene is selectively oxidized to benzaldehyde using chromyl chloride (\( CrO_2Cl_2 \)).
Step 2: The reaction proceeds as: \[ C_6H_5CH_3 + CrO_2Cl_2 \rightarrow C_6H_5CHO \]
