Question

Oxidation of Toluene with chromyl chloride followed by hydrolysis gives Benzaldehyde. This reaction is known as

• A. Kolbe reaction
• B. Stephen reaction
• C. Cannizzaro Reaction
• D. Etard Reaction

Hint:

In the Etard Reaction, toluene is oxidized using chromyl chloride and results in benzaldehyde after hydrolysis.

Answer 1

The Correct Option is D

The Etard Reaction involves the oxidation of toluene (methylbenzene) with chromyl chloride (CrCl₂) in the presence of aerated conditions. This reaction is followed by hydrolysis, which produces benzaldehyde (C₆H₅CHO). This is an example of an oxidation reaction that transforms methyl group on toluene into an aldehyde group. The reaction mechanism proceeds through the formation of a chromium complex, which leads to the selective formation of benzaldehyde. Thus, the correct reaction is the Etard Reaction.
