Etard reaction is a method of preparation of benzaldehyde by oxidation of toluene. The oxidizing agent used in this reaction is:
- A Pyridinium chlorochromate
- B Chromic oxide
- C Potassium dichromate
- D Chromyl chloride
Answer & Solution
Correct Answer
(D) Chromyl chloride
Step-by-step Solution
Detailed explanation
The Etard reaction involves the oxidation of toluene to benzaldehyde. The oxidizing agent used in this reaction is chromyl chloride (\(CrO_2Cl_2\)) dissolved in a non-polar solvent such as \(CS_2\) or \(CCl_4\). The reaction proceeds via the formation of a brown chromium…
