Identify the correct reagent for Etard reaction.
- A \(\mathrm{CrO}_2 \mathrm{Cl}_2, \mathrm{H}_3 \mathrm{O}^{+}\)
- B \(\mathrm{Pd}-\mathrm{BaSO}_4\)
- C \(\mathrm{CrO}_3, \mathrm{H}_3 \mathrm{O}^{+}\)
- D \(\mathrm{SnCl}_2, \mathrm{HCl}\)
Answer & Solution
Correct Answer
(A) \(\mathrm{CrO}_2 \mathrm{Cl}_2, \mathrm{H}_3 \mathrm{O}^{+}\)
Step-by-step Solution
Detailed explanation
The corfect reagent for Etard reaction is \(\mathrm{CrO}_2 \mathrm{Cl}_2, \mathrm{H}_3 \mathrm{O}^{+}\). In case, the side chain contains a group higher than \(-\mathrm{CH}_3\) group, the end carbon atom of the chain is oxidised by \(\mathrm{CrO}_2 \mathrm{Cl}_2\) to…
