Which following reagent is used in Etard reaction?
- A Chromium chloride
- B Chromyl chloride
- C Chromium oxide
- D Chromic acid
Answer & Solution
Correct Answer
(B) Chromyl chloride
Step-by-step Solution
Detailed explanation
Methyl group in methyl benzene (or methyl arene) is oxidized by oxidizing agent chromyl chlơride in carbon disulfide as solvent, to form a chromium complex, from which the corresponding benzaldehyde is obtained on acid hydrolysis. This reaction is known as Etard reaction.
