The main reactants involved in Etard reaction are
- A Toluene \(+\mathrm{CrO}_2 \mathrm{Cl}_2\)
- B Toluene \(+\mathrm{CrO}_3+\left(\mathrm{CH}_3 \mathrm{CO}\right)_2 \mathrm{O}\)
- C Toluene \(+\mathrm{Cl}_2 / \mathrm{hv}\)
- D Benzene \(+\mathrm{CO}+\mathrm{HCl}\) Anhy. \(\mathrm{AlCl}_3\)
Answer & Solution
Correct Answer
(A) Toluene \(+\mathrm{CrO}_2 \mathrm{Cl}_2\)
Step-by-step Solution
Detailed explanation
In Etard reaction, chromyl chloride oxidises methyl group to a chromium complex, which on hydrolysis gives corresponding benzaldehyde.
