Vedclass · Answer

(B) The reaction involving $CrO_3$ and $(CH_3CO)_2O$ at $273-283 \ K$ is the oxidation of toluene to benzaldehyde via a gem-diacetate intermediate.The reaction involving $CrO_2Cl_2$ (chromyl chloride) in $CS_2$ is the Etard reaction,which also oxidizes toluene to benzaldehyde via a chromium complex intermediate.Therefore,reagent $A$ is $CrO_3$ and reagent $B$ is $CrO_2Cl_2$.

In the given reactions,identify the reagent $A$ and reagent $B$.
