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…
