$-CHO$,Etard reaction

Vedclass · Answer

(B) The given reaction is the oxidation of toluene $(C_6H_5CH_3)$ using chromyl chloride $(CrO_2Cl_2)$ in the presence of $CS_2$ or $CCl_4$ as a solvent,followed by hydrolysis.This reaction is known as the $Etard$ reaction.In this process,the methyl group of toluene is oxidized to a benzaldehyde group $(-CHO)$.Thus,$A$ is a chromium complex intermediate,and $B$ is benzaldehyde $(C_6H_5CHO)$.

$C_6H_5CH_3$ $\xrightarrow{CrO_2Cl_2} A$ $\xrightarrow{H_2O} B$
The functional group present in $B$ and the name of the reaction are:
